17 Warning Signs Your Mitutoyo Calipers Are Fake

[@whatyoudo9773]

the battery test and off-set screw holes are the only useful differences here and I was expecting the entire vid to be about accuracy....if they are just as accurate who really cares? Would I throw perfectly functioning calipers in the trash if the font was not right??

[@Clough42]

Mitutoyo has spent decades developing and improving the digital caliper, and the result is a quality product that people are more than willing to pay for. They're creating value. At the same time, other companies are making alternatives with various levels of price and quality. This provides many options that are less expensive, and are good enough for people who don't want or can't afford the Mitutoyo. These companies are creating value. They're also providing a competitive force that keeps the price of the premium product reasonable. The counterfeiters are creating confusion so the buyer can't tell what they're getting and can't make an informed choice. They're not creating value; they're creating waste. They're also diluting the profit incentive for companies like Mitutoyo to make the next big thing that makes our lives better.

[@ligius3]

The cheap ones are probably untraceable, so not useable in a commercial shop. The battery lasts a bit less than one year, just preventing you from finishing that project while you go look for a replacement battery. Accuracy is almost the same. Disclaimer: I use the cheap ones, but they cost a lot less since they don't have any fake names. Added a switch to one, so I can turn it off. Another one is in its box, battery out, spare battery nearby. And the third one probably has a dead battery.

[@jb11547]

Accuracy is not such a simple question. How accurate is it over time and temperature variations as electronic components drift? How accurate is it after experiencing the normal handling and contaminants that get into the device with normal shop use? How will reading be affected by the start of a low battery condition that the product does not warn you about? Even the better quality electronic calipers can have measurement errors if they are not kept very clean, but it will be interesting to learn how lower-cost and counterfeit products compare in this aspect. With counterfeit products, nobody knows who made them, so the manufacturers don't care about what happens 6 months later.

[@g.tucker8682]

@@Clough42 Well said. Put another way, the counterfeiters are freeloading off the original makers' engineering, product design, package and graphic design, and more importantly their good name.

[@mm981kcolg]

Part of my work duties are calibration and I've caught and rejected several counterfeits that were brought to me by employees purchasing personal tools. This can't be shown on the video but the counterfeits all had notably grittier, rougher, and less consistent feel to them as you slide them, genuine Mitutoyo calipers are very smooth and consistent, and require only a gentle touch to move. Calibrating the genuine article will yield results that mirror the certificate very closely if not exactly due to them actually testing the tool, while those on fakes tend to be completely made up. A big tell that James missed is that the scale on the genuine calipers has a very fine semi-gloss finish and the counterfeits are much courser and rougher matte. A smaller one is that the genuine calipers have red lacquer keeping the adjustment screws from turning. Unfortunately I've seen the quality of the counterfeits rising as time goes on, though the extremely fine attention to detail that Mitutoyo has is still very much unmatched. Amazon is not a completely reliable source, I've personally received both genuine and fake tools off the site.

[@planeiron241]

Yep Mit's are smooth as silk, we use the fine points at work and I always loved getting a new pair out of the box so smooth and fine to use, nothing is like a Mit except a well tuned Tesa, they are like glass and hard to find one tuned in Dial caliper..gears are lapped and you cannot feel them mesh

[@davidwickboldt712]

After going through 2 pair of mits because of coolant, I will go with no names or off brands. Yes the Mits were rated for coolant and were fine for a few years before I could not revive them after coolant got in. My regulars are 25 dollar no names that were given to me as a joke. After I disassembled and cleaned them well. Then put them together and calibrated them. They are smooth and read as well as calipers can. Yes some are only worth their scrap metal value, others will do a fine job.

[@genixia]

@@bw1532 Yeah, Amazon are bad for doing that. When a manufacturer puts an item on Amazon they agree to let Amazon use their marketing and sales imagery and IP to sell that product *from any vendor*. So when you click "Mitutoyo" and think that you're going to the Mitutoyo store, you're actually going to Amazon's storefront for Mitutoyo products being sold by anyone. Amazon effectively allow counterfeiters to use manufacturers intellectual property to market and sell counterfeit goods. A favored tactic is to sell the item out of a port-city warehouse in the US for low/zero shipping cost, but then to require returns to China or India at high cost. Amazon will usually step in and refund without the return, but it's hassle. It's always important to look at who the product is actually being shipped from on Amazon. The manufacturer or reputable vendor is ideal. Amazon fulfillment are usually ok too, although I have had them ship me a counterfeit before. (I ordered a quality brand pair of Kevlar shears, they shipped me a two-pack of cheap sewing scissors. The replacement was correct though.)

[@porthose2002]

I noticed two other small differences. The background color of the LCD display is yellowish on the eBay calipers, but the genuine ones are silver. Also, the black labels on the ruler (fixed) is matt, while the eBay ones seem to have a texture to them. Great video, James! Thanks for sharing. I would also be interested in a test of their precision if you have an opportunity to test that.

[@kylewellman402]

Was going to point out the same thing.

[@aceroadholder2185]

I have 30 year old Mitutoyo and 10 year old Harbor freight digital calipers I use daily. They both work fine. Everyone who has used name brand calipers know the fit and finish are good. The HF calipers needed sharp edges on the beam and the slide dressed with an oil stone, but for $10 on sale there wasn't much to complain about. Say what you will about HF, they don't try to deceive you as to who made their products. If purchasing calipers, micrometers, or dial indicators I would open the box at the store and check to make sure the jaws or mic spindles close cleanly . Battery life in both calipers is usually three or four years. I do, out of habit, always turn them off with the power button. Neither has memory so that may explain the longer battery life. Being an old guy who used mechanical dial calipers way back when, I always wipe the jaws and reset "zero" every time I use the calipers. In the shop trash would get into the dial caliper beam rack and cause the indicating needle to jump a tooth often resulting in spoiling the workpiece. Buy your bargain tools from a reputable dealer like HF, Shars, Little Machine Shop. If your tool is defective, they will replace it. You are only saving a couple of dollars with Ebay or Amazon counterfeits and if something isn't right, you're just left urinating into the wind . There is something to be said for buying Starrett, Mitutoyo, or other quality manufacturer's tools... after 25 years you won't be able to remember what you paid for it.... but the quality will still be there.

[@MrSloika]

Calipers are not for precision measurement anyway. Micrometers are for precision. When all you need is 'close enough' like in woodworking, the HF calipers work a treat. And if you drop them and step on them? No problem, back to HF to buy another one.

[@chemech]

@@MrSloika Precision actually means repeatable, while accurate refers to how close the measurement is to being true. An improperly calibrated and/or zeroed mic will still feed you precisely the wrong number all day. Also, dial or digital - or even vernier! - calipers are mostly way too accurate for woodworking, while being quite adequate for many machining operation and layouts where +/- 0.003" is all that you need.... sometimes even down to +/- 0.001" If you are working on optics, or something similar, by all means, get out your mics... and check their calibration against a standard! Why yes, I have had mics get out of adjustment between uses...

[@JJFX-]

The metal HF calipers are well worth it IMO. I did the same thing to clean them up and have used them nearly every day for at least 2 years. However their digital micrometer is a steaming pile. It was fairly accurate when it first worked but the plastic mechanisms quickly deteriorate and break.

[@jed-henrywitkowski6470]

@@chemech I'm not a manufacturer of aerospace components, so I don't need the absolute highest tier of measuring instruments. However, I do appreciate the robustness of steel and do need equipment that is going to consistently be more accurate than "eyeballing" the workpiece.

I have a genuine Mitutoyo 6" purchased from MSI-Viking (an authorized reseller), but mine was purchased in 2009. Some notable similarities to your newer models: fit/finish is excellent, end-milled recess in the back, nice plastic molding, ABS visible in the battery compartment, two contacts visible on the PCB. However, a few differences which are actually more similar to your knock-offs: The yellow swoop ends above the S, not the O of ABSOLUTE on the front. Battery insertion goes straight to 0.00mm, or a completely bogus number if left for a while first, not flashing dashes Origin button is recessed, top of it is flush with the top of the plastic on the front. screw alignment of one hole is is ok, the other is not great. So it seems the knock-offs may be copying some older models (poorly)

[@hankcohen3419]

I too have a 150mm older model with exactly these same differences. On all other points they match with James' description of the genuine article.

[@apsilonblue]

I agree, I have a set here at my desk that are only 5 years old and I'm confident are genuine and the certificate has the high print quality but the same T Suzuki QC manager and the Ferrobrite sheet looks very similar to the knock offs shown here so it looks like they've copied them from a few years back. Everything else is a match for the new genuine shown here.

Yeah same. I have two contacts etc. but no white writing on label and off centre screw holes. Mine is genuine (all other tells are aligned with your genuine) so I think probably the knock-offs are mimicking an older model. I’ve had the same battery in for the last 5 years

[@robroysyd]

I have an over 40 year old Mitutoyo dial caliper. No battery issues ever with that. I really agree with your comment about why use another company's name when you're actually making a decent product that fills a need within the market? At least to some extent this does seem to be happening with Banggood.

[@gorak9000]

Because if they sell it as the Bang Ding Ow company calipers, they're only worth $12 like the other cheap generics, but if they slap some fake mitutoyo stickers on them, now they're $100 calipers

[@robroysyd]

@@gorak9000 How did Mitutoyo become to be a respected brand? Remember when very, very few people would buy a Japanese car? Look at Japanese cars now. I've got a couple of cheap Fluke instruments made in China that are actual Fluke products. They were made in China for the Chinese market, some leaked outside the border via eBay. Sure maybe some will be fooled into thinking they're getting a real bargain buying a Mitutoyo for $100 but whoever is making these would sell a lot more at $50 and build a reputation for their own brand.

[@SianaGearz]

@@robroysyd Well you see a lot of slightly premium-ish (above $12, below let's say $40) priced calipers on Ali which are some seller's or factory direct brand, and by all reason, some or many of these probably share production with these fakes, but might have extra benefits such as better QA etc, if the seller isn't here today gone tomorrow type of deal and actually intend on building their brand - sellers of fakes have no intention of processing customer complaints long term, they rather disappear. I think there is a sort of saturation, there's a lot of these brands, and there's only so much product you can sell that way without access to large distributors and retail. This opens a window for some small operation to order a fake product and make a killing selling it to likely largely unsuspecting buyers. I think a lot of people, maybe hobbyists etc, heard that Mitutoyo is a good brand but they don't know who distributes it legitimately and how much it really costs, so they see and grab and that's it, and they don't have alarm going off in their head because $80 appears expensive enough for a premium tool. They have some recourse if they notice, but that's effort and distress, so they may decide to not care. So i think it's not an either-or situation but an and-situation.

[@twistedhillbilly6157]

I was always a Starrett man and I only bought one Mitutoyo tool in my 22 year career. It was a 24' dual beam dial caliper (built like their height gauge) that I bought in 1980(?) As I watched this video, I had a Harbor Freight (CEN-TECH) 6" digital caliper in front of me. I paid $19.95 almost 20 years ago. As you went through details, so did I.. Almost everything that was sloppy in your fakes, is much cleaner on my cheapo HFT. I heard that Harbor Freight has grossly down graded what they sell now, but these old models are pretty good especially for ther price.. I sold my 24" Mit's on EBay 10 years ago and the guy that bought them was ecstatic at the quality and workmanship of the tool. I had built a custom case for them and engraved my initials in several places, The buyer happened to have the same initials as me, and he got the case too... I don't remember how much I paid originally but I think I might have gotten a little more when II sold them... .BUY QUALITY and you'll never be disappointed....

As the channel owner said, if your product is almost or close the original - compete on price. They can't. I bet they make much more money on the fake than on their own brand which is lost in a sea of similar competitors. Here's the simple fact..most people don't need a Mitutoyo..makes you feel better? go ahead...but unless you're working for SpaceX you don't need it. Buy a much cheaper no brand one and move on.

Another benefit, if it something that is useful to you, you can get them to measure fractional inches as well. All for a much cheaper price. If I were you I would keep the Mitutoyos for your shop but try the iGaging for the other uses.

Yes that definitely happens if the seller chooses to co-mingle items. They can even have Amazon put a label on it. Usually if they come from the closest seller, there will not be an fnsku label on it (the specific seller label they can track) and Amazon just goes by the UPC code. Fakes can be a big problem but if you get one, Amazon will usually make it right.

Quick heads-up that on some of the (possibly older) genuine digimatic calipers- I have a 500-196-20 here- the 'origin' button is actually recessed a little and there is a sculpted recess in the top cover to allow that button to be pressed, presumably so that it's not easy to press inadvertently. I have a newer 500-196-30 and that doesn't have a moulded recess, but the button is lower than the other three. So just wanted folk to be aware that a lower 'origin' button should not be used as a differentiator in isolation to all the other excellent points made here- great video.

Thank you for a very useful video. There appears to be different grades of the fake callipers. I have one that passed some of these checks. The case and documentation was the same as the genuine unit. The thing that alerted me to the possibility that my calliper was a fake was because the battery didn’t last very long. Your current drain test was most useful. I had intended to do the test before I saw your video but having you current readings was particularly useful. My fake draws 15µA when on and off. An interesting thing about my fake is I have had it for several years and it’s an older version 500-196-20. A genuine seller listed the later 500-196-30 but still had the photo of the older 500-196-20 on their website. The tale on graphics is short and is the same as on my fake so I suspect the graphics has changed between 500-XXX-20 and 500-XXX-30 and the fake makers have not updated their artwork. I just bought a genuine replacement, which passes all the checks. The confusing thing is the price offered by genuine sellers vary enormously.

[@nagi603]

Another thing: the surface of the printed scale is rough in the counterfeit items, while smooth for the genuine. Also the printed scales stop just shy of the end, right under the pinning. Not so for the fakes. 27:57 Note that those tiny QR codes are basically useless on the fakes, while perfectly readable (though small) on the original

[@Sembazuru]

I was going to mention the QR codes. My phone was able to read the QR codes on the two genuine Mitutoyo off the screen and it was the three lines of identification: Code#, Model#, and Serial#. The QR codes on the fakes not only are muddy and unreadable, but they appear to be identical. I'm at work so I don't have access to my Mitutoyo for me to check the QR code. And, I can't check my coworker's Mitutoyo because the calibration sticker (it gets an annual 17025 calibration unlike my personal one) covers the QR code.

[@jeremylastname873]

“Mitutoyo” (on the caliper image) is missing from the yellow/red “first” tag. I worked in anti-counterfeiting and can tell you that people will go to amazing efforts to take advantage of a successful product. If they put the same effort into honest labor, they’d probably make better money.

[@billshiff2060]

No they wouldnt, because what they are actually stealing is the money Mitutoyo as spent developing their reputation as well as the money they spend manufacturing high quality instruments. They might make a good product but no one will know them.

[@RIPPERTON]

Yes at 15:12 the mitutoyo logo just above the battery is missing from the fake. Also note that Clough doesnt notice this.

[@ScytheNoire]

The date on the counterfeit batteries has to be trolling with the 4-20. Great video, very useful. Stumbled upon it as I am looking at getting a better set of calipers, since the cheap ones I got never quite give the same results, and sometimes can completely lose the measurement scale.

[@zoide-777]

Great work on doing the current comparison, this is relevant even for the non-fake cheapies - when you go to use them the battery is always flat. Sadly. Also great shout out to @EEVBlog using his meter :)

As always, thanks James for an interesting comparison. One very minor difference you didn't mention is on the Yellow 'Battery' tag... The ebay ones do not have Mitutoyo printed above the battery compartment whereas the genuine ones do, just as the actual calipers have on them.

[@DanielSallros]

Hi James. Great video! I have a few more things that differ between the genuine Mitutoyo calipers and the fake ones: - The thumb screw that locks the caliper is much thicker on the fake calipers - The end stops are not located as close to the end of the caliper as they should be on the fake calipers - Mitutoyo 12" calipers are much thicker/wider and uses a completely different electronics/plastic housing - The angles of the jaws/tips are much steeper/different on the fake calipers compared to the genuine ones

I didn't read through the comments as I'd imagine I'm not the first commenter to bring this up - - although hinted at, the most obvious question was not addressed here - that is: given a known object to measure, do all 4 calipers give accurate readings? Not to be misunderstood Clough, this was an EXCELLENT video presentation - butttt

[@НикитаАндреев-ч1ь]

Hi, I watched your video, thanks. I just received a mitutoyo caliper from a dealer in Italy, ordered in early August. I am 90% sure that this is the original, but there are some differences such as: 1. The color of the scale (the scale gives off green) 2. The color of the box (the box is darker in color, like on the ebay caliper, but the stripes are gray and parallel to M) 3. The inscription "Made in Japan" on the case is not on the side of the hinges, but on the side of the latches. 4. The abs marking is not under the battery, but on the back of the cover, the position of the battery with the marking is also shown there. If interested, I can take a photo for you, maybe there will be more videos on this topic?

[@jonathanramsdell906]

Just watched your video, and was curious to take a critical look at my older (ca. 1987) analog Mitutoyo 6" calipers. It's worked perfectly for thirty-odd years, and seems to be well made. I did, however, notice that the fixed jaw did not have a chamfer, unlike the digital version. Thanks for getting me to go take a close look!

[@cynic5581]

The tech used in digital calipers has been refined to the point where it’s hard to mess up. Bigclive did a good video on how cheap calipers can be so accurate with such a high resolution. Knock offs will spend the vast majority of their design cost trying to rip off Mitutoyos look so they can charge over 100 times more than it cost to manufacture them. Honestly it’s hard to justify Mitutoyo when it comes to calipers unless you have the disposable income or your employer is buying them. I use a company provided Mitutoyo 8” caliper to verify the calibration of my inexpensive Amazon calipers I use in the field. They are always spot on. Only thing I would suggest is just going straight for less expensive calipers with their own brand name so you aren’t paying for nothing. Something I wish inexpensive brands would do is use a better tech when it comes to battery life or just put a compartment for a triple A battery in it or something if the lower power tech is expensive.

[@ewildgoose]

I would point out that many of the mitutoyo are IP rated and coolant safe. My favourite chap brand are igaging and their cheap ones aren't coolant resistant. They do a more expensive version that is, but not at a discount over the mitutoyo... I think it's useful to have lots of calipers.. get a few decent low cost options and keep the mitutoyo for when you need to do inspection quality work?

[@odinata]

I agree. This guy inherited some money. He's got expensive toys.

[@wilde.coyote6618]

I don't mind investing in expensive tools. When I quit my job, they go with me. I think my 9 to 5 boss would like these calipers. It complements his cheap Chinese lathe.

[@tookitogo]

Oh, not all all cheap calipers are good. I have some I got at Aldi and they’re unusable. Aside from the ludicrous battery consumption, they skip readings, so eventually you’ll be off by some multiple of 0.2” (5.08mm). Easy to spot when you’re measuring something half that size, but not at all obvious when you’re measuring something 3” across. Screwed me over more than once.

[@2OO_OK]

That was very interesting. If you could do the current draw test on the shars that would be great. And no, I don't think that shars being a sponsor makes your reviews fake.

[@MrRctintin]

Totally agree, who cares if Shars sponsor the channel.

[@rogerrascal8632]

Check the serial number from the caliper to the certificate to the box- all should match. Check the locking knob on the genuine unit won't unscrew all the way out, the fake one does, otherwise a great video. You also proved why my fake Mitutoyo goes through so many batteries!!! Cheers! buy GENUINE!!

[@christopherwillson4269]

Excellent video! Thank you. If and when I ever needed to spend the money on Mitutoyo instruments, I would absolutely want to be sure of getting the genuine article. Counterfeiting is a plague that degrades the value of the real thing. For my needs I can get by with more affordable options, but that doesn't make these fakes any less heinous. I especially appreciated your attention to the differences in branding quality and color in the packaging (I'm a printer) You've earned a new subscriber.

[@simonwolfsgruber5948]

Something i noticed using a genuine Mitutoyo Caliper were the perfect parallel jaws. If ii's well cleaned you can't see light shining throuh the gap of the two outer jaws. Furthermore if you have set the origin correctly it's nearly impossible to push it to a negative valiue - in comparison with cheap ones where you can push it up to -0,05mm. The second thing i noticed . Cheap calipers sometimes lose the origin point after really fast jaw movements. (But i think that's only a Problem with non absolute calipers.

Thanks. You are absolutely great in your presentation. Lots of time and dedication. This is very favorable. What I like the most about this video is the suggestion for counterfeiters to make their own product If they got to a point where they believed that they are great in their manufacturing . I am personally switching most of my items to US, Japanese and European made only items. I know it is very hard and expensive but I am definitely besides being against counterfeits, as well as an abused kid from overseas, against countries that employee under aged kids for the absolute benefit and egocentric care of their self interest.

[@Larrye123]

Thank you for making the video. I'm so glad I have a real Mitutoyo caliper from 20 years ago. The machining on mine is flawless. It's hard to believe that in the twenty first century with CNC machines we have this horrible quality of tooling AND fake tools.

[@drycreek3204]

Great video with details that show obvious difference. I noticed that the strip on the bar was rough looking.

[@tedcook5197]

Modern genuine Mitutoyo calipers use inductive sensors which should be immune to a little water or oil getting on the scale. I'm not sure, but I would bet the knock off calipers are using capacitive sensors. It would be interesting to see a test of what the display does after getting a bit of coolant on there.

[@N1gel]

Yes capacative sort of Big Clive tokk some apart a couple of times so did somebody else about 5 years ago. The calipers had similar to vernier fingers so that as they slide to measure - only 1 pair of fingers align perfectly. But I believe it was Clive that suggested they were using capacitave coupling to couple a transmit oscilator to a receiving finger and scanning the fingers for max signal to equate to a lookup table. However they were surprisingly accurate when re-assembled even with parts missing and glued strips pealed off. Somebody copied the scale to cad and made an extrapolated pcb about 2 feet long and it worked properly in the ripof calipers.

[@ElectricBillAlbright]

Or in worst case they might use a potentiometer (variable resistor). Optical shaft encoders, using infrared light pulse as it rotates or slides. I don't know if they could get ten thousandths or finer accuracy though.

[@SianaGearz]

@@ElectricBillAlbright Nah resistive sensing is just not a thing. $3 calipers (the plastic 0.1mm ones) are already capacitive, once you have an ASIC, and they do, shared across all these brands and models and manufacturers, that's just cheap, and does the job. Optical isn't cheap, finicky to get the process right. All they need for capacitive is two PCBs (flex under the scale sticker and rigid for the toolhead) and a gloptop ASIC, and the PCB quality they do is bloody filthy and they're still getting away with it, kinda works. Holy shit that resist application and via termination, it's beyond terrible. And yet it works.

[@paul.newland]

Other easily visible differences I’ve noted are that the locking screw is machined differently and the riveted retaining plate on the end of the beam is in a different location, further from the end. I have a number of cheaper brand calipers (not fakes) and a 6” and 8” pair of genuine Mitutoyo’s. The cheaper ones are maybe just as accurate but live on the lathe headstock or the mill table, get used occasionally as a pair of dividers and are considered disposable items. The Mitutoyo’s are considered metrology instruments, are used during the design process to evaluate existing components for fits etc. Both of these slide like they’re on melted butter and are a joy to use, unlike the others. If you place any value on what you do, you probably already have or need to experience the genuine items, but why pay elevated prices for fakes to kid yourself that they’re equivalent? Simply buy the cheaper non fake items if you don’t place any value on the differences!

[@jamiemacdonald436]

Yes, I noticed the riveted retaining plate as early as the initial picture at the start of the video.

[@rasungod0]

I was following along with my calipers and I knew they were real but since I bought them on Amazon there was always a tiny bit of doubt. Now I can be 100% certain mine are genuine.

[@michaelclueless]

Thank you for this detailed comparison; you sound like me! :) I don’t need a precision caliper in my work, but I do use a dial caliper. It gets dropped and mishandled; I frequently hand it to customers to give them more confidence in their readings. At home, I keep a better caliper, but not a Mitutoyo; it’s marked “Anytime Tools,” and the instruction sheet is dated 2006. No nation of manufacture is indicated, but the company address is in the U.S. It reads metric and English, with a needle on the dial that goes halfway-around for one millimeter, and another needle that reads a tenth of an inch per revolution. The linear scales are clean and accurate. The case is adequate, but it seems that it may open if dropped, so I keep the original cardboard sleeve around it. I don’t like battery-powered instruments because I hate having to hunt down replacements. At my age, I hope never to need a replacement, but I am thankful that you showed us what to watch out for!

[@marcmckenzie5110]

@Clough42, thanks for making this. A year ago I watched this when you released the video. A couple months later I ordered the 4” pair from an Amazon seller, lo and behold, it was a copycat.

If these are true indicators of counterfeit products then the Mitutoyo Store on amazon is also selling fake products. I bought a dial caliper from the Mitutoyo store on amazon and some of the packaging "flaws" are present such as line thickness and Serif on the R, but the angle, logo (snowman) and color are all correct or I should say they match what he is saying above.

[@shannonstapleton]

I appreciate the detailed in depth nature of this comparison. I also understand the purpose to demonstrate the visible differences between a genuine product ad a counterfeit. I have seen this on Amazon particularly with camera equipment. I'm a little disappointed that there wasn't a comparison between the accuracy of the genuine and counterfeit. I would encourage everyone to avoid companies that trade on the work of others. It is immoral to support theft. I am just curious. If you end up buying a counterfeit product, whether by mistake or not, did you at least end up with a tool which does what you purchased it to do?

[@wayneschenet5340]

Totally agree with your analysis. A more meaningful comparison would have been the accuracy comparison. Best to buy from a known authorized supplier to get the genuine article. I’m surprised that US Customs do not confiscate the fakes, like they do with the Guicci bags?

[@hwingerrr5680]

An accuracy comparison would be better able to quash the desire for the knockoffs if that's the goal here. Being able to show functional differences and deficiencies along with the more readily identifiable differences like fonts and packaging tints would convince the majority of the viewers to avoid making the wrong decision.

[@frankburdi1001]

Your observations are a blessing because I recently bought one and I'm a long time toolmaker who has owned only genuine tools' whole life I happen to have bought a 8 inch off of eBay which is the genuine article thank you so much

[@Arek_R.]

I'm glad to find out that mine I bought off ebay for like half of the price are genuine on all counts. Other differences I can see from your fakes is that the QR code on the back looks like something that is too low res to even get scanned. There is also sprue mark in the battery compartment in the original and its absent in the fake one. Label scale on original one is mostly smooth, fake one has got texture. Also props for the eevblog meter.

[@MiniLuv-1984]

That was good "spot the difference" there. I too would like to see actual measurements and hardness testing of the work surfaces. I completely agree, they should just use their own brand, especially if the metallurgy and accuracy are comparable to the Mitutoyo. Battery draw is a pain though. I have a Mitutoyo vernier callipers from the early 80's. Battery hasn't gone flat yet. :)

[@williammurphy8227]

16:00, the yellow labels are missing Mitutoyo in the drawing of the caliper. I bought a Mitutoyu 6” vernier caliber and 1” micrometer two years ago from a local industrial supply shop. These were apparently sitting in the store for several years. The caliper’s box cardboard box top surface’s orange ink had completely faded, so the orange test didn’t apply. The print was difficult to see, but matched nicely. The case said made in Japan. The certificates looked genuine. The details of the battery compartments were not the same as your calipers. The print on the caliper’s rules were completely different. My caliper’s battery indicator is giving a B and must be a low battery. Thanks for the details.

A tip to save battery is to always do up the lock screw when you turn it off. This will stop the calliper from moving and turning on automatically when you didn't mean to.

[@AlainHubert]

I paused the video on the first picture of the 4 calipers, and right away I could tell which was which by the small riveted plate at the end of the calipers. On the genuine Mitutoyos, it is straight and very near the end, whereas on the counterfeits it is somewhat crooked and not quite at the end of the calipers. Great demo, thanks! BTW, my 24 years old genuine Mitutoyo 8" caliper isn't quite the same as modern ones, it also came in a light grey plastic casing instead of black, but performs as well and is very reliable. It should be, I paid $120 back in 1998 for it!

[@mickscully9558]

Something else to keep in mind is that the original Mituoyo gear will last a lifetime. I got a 6" Mitutoyo digimatic caliper in 1990 - at which time I think digital calipers were pretty new to the market and looked like witchcraft to me. Anyway, 33 years later, they're still doing a flawless job - maybe the fakes will last that long... maybe.

[@inductivethinking]

Actually the typical cut‐off voltage (i.e. the threshold they use for measuring battery capacity) is 1.2V for SR44 cells. So the fake ones work as expected, despite the lack of battery low indicator. It would be interesting to see if the original calipers work down to 1.2V without producing errors. Perhaps you could check?

I'm pretty sure Mitutoyo changed the button height on the origin button somewhere along the way. I have a 6" caliper from ~2014 that has a recessed origin button. Same with an even older pair I have (non -AOS). As for the test certificates, I think Suzuki-san retired somewhere along the way because they signed my 2014 pair. Also you missed another detail on the backside of the cases. The genuine cases have support ribbing from the edges.

Excellent advice. Years ago I bought expensive Sennheiser headsets on Amazon. They sounded terrible. After much research, yep, counterfeit. Contacted Sennheiser and they directed me to an authorized reseller. Bought the next pair from them and... yep... another fake made it into what was believed to be a solid distribution channel. Contacted Sennheiser again and they sent me a pair straight from the factory. They sounded incredibly good. I compared the real units to both fakes, including packaging, colors, shapes, sizes and feel of the materials used in their construction, and they were all identical. I surgically opened the fakes up and could see that the internal noise-making bits were horribly constructed by hand. Always good to talk to the manufacturer when laying down good money for their products and ask where to buy, but also for their assurance on how you can be confident you are getting a genuine article from their distributor.

Great video I really like the attention to detail. I’ve read several of the comments and some I agree with and some I don’t . Personally if I am paying for Mitutoyo then I want the real Mitutoyo. Imagine if you were to go to a Dodge dealership and order a new Dodge Charger with all of the bells and whistles. You sign the papers and expect to get a Dodge Charger but when they bring you the car, they give you a ford pinto instead. Sure the pinto will get you from point a to point b but it’s not what you ordered.

Could not possibly have asked for any more detail. Excellent! I have made the same purchase and analysis.

Another small difference with the battery instructions on the fake Mitutoyo caliper is that the brand name is missing on the illustration of the counterfeit caliper. This can be seen at 15:22 on the video. You have done a really thorough job comparing the genuine and the fake. I watched the entire video from start to finish. Fascinating. The really scary part is that these EBAY fakes will have no product support ! If they break down the money invested in them is lost forever.

Love your almost obsessive attention to detail here. I think investigating the difference in accuracy and precision is a worthwhile cause. Your point is excellent -- yeah it's fake but is it a decent tool? Some fake Hakko soldering irons are circulating, but when we tore them down, the internal parts and construction are better made. I wouldn't buy one but it's possible that the fake represents better value!

It appears they knocked off an earlier model of the Mitutoyo 500-196-30, mine date late `80's, early `90's. Mechanically, they match your knock offs, from the inside jaw grind, the back groove being ground vs milled, to the yellow swoop being over the 'B' vs the 'O'. As for the digital readout, mine has the absolute button bellow the surface, you need a blunt toothpick to poke it. The ON/OFF, ZERO/ABS are on the bottom, not the front (it actually makes more sense than the newer ones). Internally, all exposed connections are gold plated, the face is glass, the board has the appearance of carbon fiber. The fit/finish though on mine is flawless, literally took a lightening strike to my garage to kill them (may they RIP). The 'thing' that holds/supports where the rod protrudes at the bottom has beautiful rivets and is ground flush. Great video, just thought I'd share so anyone who has an older pair didn't get disparaged thinking they 'definitely' had a knock off. The battery, my Horrible Freight ones, I have to flip the battery over if I'm not going to use them for more than an hour they are such pigs. My Mitutoyo, every few years the battery needed replacement.
