Dave found this crazy bargain of the century no-name $9 0.02% class multifuction process calibrator on Aliexpress.
Is it any good?
Actually, it's an AIMOmeter AMPX1 that sells for over $200 on ebay, so what gives?
How can they possibly manufacture and sell a 0.02% class device for under ten bucks?
Teardown time.

UPDATE: It looks like all sub $10 meter have sold out after about 300 units. Cheapest price now is $60 or more, and some buyers that snagged one at the low price have said the seller has come back to them and asked them to make up the difference in what the real price should be, and to pay an extra $65. So sorry, looks like the party is over. dhgate still have it at around $20 apparently.

That's the most logical explanation. Units that failed quality testing, some might be close to fully working with a minor issue, others close to useless.

[@FlameRat_YehLon]

IIRC it's usually a violation of contract or brand infringement for the manufacturer to sell those themselves, and thus the debranding thing might just be to avoid brand infringement or things like that. Anyway, people who buy debramded stuffs usually know that it might not work properly so it's more of a gamble than a scam.

[@spehropefhany]

Maybe returns from a wholesale customer.. they made the case a different custom color from the original green for them.

They were trying to sell these to other companies like BSIDE as you see the same meter sold by many names. Maybe they didn’t sell so the scratched the name off? Maybe that’s why they didn’t sell and they are going for cheap now?

[@kaumohlamonyane272]

Hey Dave, could you do a review on the FY6900 DDS function generator?

[@chrisbenton3365]

I second the motion to review.

[@LutzSchafer]

While unrelated to the shopping francy I don't expect the FY6900 much different from its predecessor.

[@steverobbins4872]

Did they gold plate the contacts for the rotary switch? Hard to tell from the picture but it looks like bare copper, which may wear out quickly. Could be why they scrapped these.

[@JaenEngineering]

It's easy to understand how it's so cheap if you look at the economics of mass manufacture. Let's say the manufacturer makes 10,000 products at $10 cost. That's a total of $100,000 in costs. Now let's assume, say 10% fail QC, you now have 1,000 faulty and 9,000 good units. You can sell the good units at, say, $250/unit, which will gross you $2,250,000, but you still have a 1,000 faulty units (with $10,000 of parts) that you're either going to have to pay to fault find and fix or pay to dispose of. Alternatively, you can just remove your branding and sell them to a discount retailer for $5 each. Now, rather than paying to fix or dispose, you just made another $5,000 gross for a total of $2,255,000 gross, minus the initial $100,000 which still nets you $2,125,000. You've only lost $125,000 (5.8%) on being able to sell every single one at full price, but you also don't incur the costs of fixing or disposing of sub par units. It's not uncommon practice, and will more than likely be accepted as an acceptable loss. It's really not that different from CPU manufacturers using faulty, but operational dies in their lower SKU lines to make up for less than 100% silicon yields. TL:DR it makes perfect sense 😊

[@davidhunt240]

Yup. These were made by MASTECH and they make millions of meters. My guess was these were made for a customer and were QC fails and rather than try and rebuild them, it was easier to sell them as scrap, hence the shredded model and serial nos. As for the pricing, I suspect many shops are run by one company, it's a common Chinese tactic to funnel shoppers into buying at an inflated price (and to make it appear a particular product is popular, when in fact only one company is selling it)

[@santopino2546]

Why would a manufacturer undermine his own $250 each market putting out the faulty units? I remember the farmers in my country prefer destroying the over production rather than selling them undercost.

[@JaenEngineering]

@@santopino2546 this isn't a matter of over production, it's about quality control. If a foodstuff fails a quality inspection it HAS to be destroyed for public health and safety, and is an irrecoverable loss. Consumer goods that fail quality inspection may still be safe, just not as functional, and therefore can be sold, thus minimising the loss incured. The manufacturer isn't undermining their market, they're just minimising their lossess as effectively as possible. Also, farmers destroying over produce is usually due to trade regulations that state they're only allowed to produce a certain amount, and can incur fines for trying to sell more that their allowance allows...

[@santopino2546]

@@JaenEngineering Whatever the reason, but does it change the fact that they would be undermining their own market? I had no problem in the past 20 years to waste thousands of Euros for good quality certified process equipment, but I know of many technicians that would immediately jump on these bargains and use them on their jobs.

[@davidhunt240]

@@santopino2546 Take your farmer analogy, if some of the produce is damaged, it will be sold to industrial customers who will turn apples (for example) into fruit juice, or mash for pies, or even food for pigs. The farmer gets less money but the farmer doesn't have to bury the crop on their land and they still get something for it (even if it is a loss) Now some of those apples might be stolen along the way by someone who thinks they can sell bruised apples for $$$$, but the market isn't being undercut as the supermarket who only buys perfect apples sells to customers who only want to buy perfect apples. There are two distinct markets with little overlap. I lived on a farm for half my life, so I've seen the impact of disasters and the cunning schemes to make money from what looks like a total loss.

[@MirkWoot]

Someone must had bought 100x or something :P sellers caught on. Or well, just a lot buying.

[@buddyryanmckendrick6601]

hi david, your exitment is hillarious. lovin it! the cheapest i found on ali express is now 88 US$

[@stevewalston7089]

Chinese branded factory reject seconds for $9 … seems about right regardless of the spec. Just how long could it last and just how well could it be built anyway?

[@johncoops6897]

It's NOT "Chinese branded"... might be an idea if you watch the video, perhaps?

[@JerryWalker001]

Interesting but they would not be manufacturing and then removing their own brand name. These are most likely second market units but definately worth picking a few up for anyone that needs one. I doubt that they will be available one the container is empty.

[@ImRichRu]

Its a Chinese 'night shift' production run...

[@delightful-ish]

Just watched this video (not sure why it didn't come up at the time) Shockingly they are all gone 😮

[@jeroen5838]

There are a few left for $40, search "Mulitifuction Process Calibrator"

[@AlexAskerman]

15 minutes after public, all up to $80, Dave's patreons cleared them out

[@jakegarrett8109]

Looked like one of his links had it $10.50 or so with $2.50 shipping (just clicked random one, like 4 up from bottom or something). Still, $15 isn’t bad... Might have to get one to calibrate a few meters I have coming. Previously I just used CPU voltages, set my board to 1.5000v (do not do this on Intel or Ryzen CPUs, I used FX, use like 1.2v for those other chips), and disabled all but 1 core so it had the least amount of load. You can also test at any known voltage (like I also tested at 1.5125v too). It’s the most accurate source I had, so if you have a high end board you MIGHT be able to do this, the problem is some high end boards have a load line calibration setting that can go way over voltage, which is kind of why I needed the meter to be a bit more accurate than just for measuring batteries, haha! If I get one I’ll have to hook it up to my high end VRM power board since I can program it for dynamic voltage loads or startup procedures and exact voltages or transistor switching frequencies etc, it should be pretty accurate (the microprocessor in it is like $50, and the mosfets cost like $85 alone buying thousands at a time, but it’s kind of needed for the 600+ amps it’s rated at on primary side with its 11 stage VRM)

[@rorypoole5582]

Any one have a dgate link?

[@sanityd1]

Ha the one time I save an EEVBlog notification for later it's a jump on it now situation. Great find Dave!

[@radry100]

fell from the truck, that's why they scraped off the name

[@johncoops6897]

If they fell off the truck, then there'd be no need to scrape off the name. Think about it.

[@squee222]

with the loose connections etc - it seems like you still get what you pay for... The items were probably deemed to fail QAQC and like you said - they fell off the truck - nothing is really thrown out in china

[@MrDehicka]

I bet only 0.02% sold will be used for actual process cal.

[@EEVblog]

LOL, yeah.

[@todesgeber]

they probably removed their own name/model off after the units failed qc, or were returned defective. then they kicked them out the back door because it was cheaper then storage and disposal. maybe "3rd shift" kinda stuff?

[@janekw.6022]

Already gone everywhere :(

[@Deepanimosity]

Found it on the US AliExpress for $94.28, maybe it was an off by 10 error. Misplaced decimal?

[@_--_--_]

500% price increase in 3 ... 2 ... 1 ...

[@chef1arjunaidi]

Nah, it didn't fell off the back of a truck. It came ashore from a container ship that ran aground at the Great Barrier Reef :-)

[@Landrew0]

Looks like a rejected and liquidated production run to me.

[@outsideworld76]

This! Probably they all have individual issues which are out of spec!

[@dannooo548]

What makes that MAX629 chip so expensive? That seems like a crazy price for anything but an integrated module.

[@electronbolt6550]

Somebody must’ve bought all of them and going to resell them at a higher price

[@thetechgenie7374]

Pretty sure that what happened.

[@volodymyrzakolodyazhny]

Dave? :)

[@ddee2501]

I bought one. Not the same but cheap and does must of the same functions. LB02 Process Calbrator

[@livebrain]

youtube only showed me your video a few minutes ago :XX all gone damn you youtube ! lol

[@excavatoree]

Dave's supporters, who get early access to videos, got them all. I jokingly suggested that Dave did this as a promotion to get more supporters, but it's probably some sort of dumpster dive.

[@Petertronic]

If it was EEVblog viewers who snapped them all up, perhaps they could club together to sell them and use the proceeds to help save FranLab. (she's got problems again)

[@therianet]

no one can save Fran from Fran, stubborn don't want to move from ridiculously overpriced city

[@Petertronic]

@Henry Herz what a nice kind person you are.

[@jenpau0269]

I bought 3pcs and they declined my payment Lol, now they cost 250usd lol

[@ArthursHD]

Likely multiple sellers got from a single source therefore they didn't have that many available in stock. Once I tried to buy last item which was not produced any more from an aliexpress shop they sent a message that item was damaged and refunded.

[@jenpau0269]

@Exodus hahahahaha, great deal so, buy more as fast as you can, that's 27usd only than 150usd lol

[@jenpau0269]

[@nihonam]

reminds me the old Moscow legend about the whole railcar of 21" CRT monitors for the price of $200 per unit in times when they were over $1000 ('90s), they vanished just before I heard they exist

[@basileus9343]

Released at 1 AM for europeans and of course they are all gone >:(

[@jeremiahlyleseditor437]

The item works well but is probably a defective unit in some way which is why it was sold that low. With the amount of techs out there, almost all of the purchasers will fix the glitches in the unit, if any. Great deal for them. The trim pot was probably for calibrating the meter to zero or whatever.

[@pooldoctorofclermontinc5788]

Cheapest I can find these for are $88 each. I'm in Central Florida of the U.S.
