Digital Micrometer From Banggood

We review the "SJF" 25mm/0-1" metric/inch digital mic, sent to us from Banggood to be evaluated. The unit was tested with a few gauge blocks and compared against an analog Brown&Sharpe mic. Performance was considered generally very adequate for such a competitively priced item - a useful addition to any home shop.

It measures up to the task.

[@ChrisB257]

Well said Harold :)

[@Xynudu]

Good review Chris. I really like this micrometer, mainly because of the easy to read display and it's good accuracy. Price wise it's hard to beat. I notice yours has two screws missing in the face panel. The mike also handles temperature change quite well without significant need to recalibrate. Cheers Rob

[@ChrisB257]

Hi Rob - haha, yes, I had actually not even noticed those missing screws. 0/10 for observation :)

[@michaelmurray9154]

I would've expected to pay more for that degree of accuracy. Nice to have a tool that you can flick between imperial and metric quickly. Guess I'll stick with my little Lufkin 0-1's though!

[@ChrisB257]

Hey Mike, Well, the value aspect certainly comes out pretty reasonable. Lufkins are good :)

[@johnkinnane547]

G'day Chris these Mics seem pretty good value, I saw the review that Rob did and these seem not to bad for someone starting out in the hobby. You gave that thumb a bloody good wack!! One thing about these Mics is the large 'read out on it no straining of eyes, good to see you again hope everything is alright regards John

[@terrylarotonda784]

Good comparison and I would give it a thumbs up. Since most of us in Home shops aren’t building space craft, I think it’s a good tool and price. Thanks for sharing my friend.

[@ChrisB257]

Hi Terry - thanks. hard to beat the price I must say. Ideal for a home shop.

[@infoanorexic]

It seems that as long as you don't go with the lowest priced option that they offer, the tools are adequate. That has been my experience with Grizzly, anyway. I got one of their

[@ChrisB257]

Indeed, there are quite a lot of very acceptable items from them - in some cases though a matter of luck! All depends too on what is actually needed regarding critical accuracy and truth etc. I too have different measuring devices for different jobs - often a vernier is adequate for initial measuring, coming on later to critical devices towards the end.!

[@shawnmrfixitlee6478]

She looks like a keeper to me , Great share Chris !

[@TinkerJohn_W5CYF]

Nice review; good info about the caliper and comparison to other brands.

[@ChrisB257]

Thanks John - a bit long perhaps but hopefully useful.

[@pierresgarage2687]

Hi Chris, For a digital it's a good price considering the accuracy, very difficult to control instruments in the tenth of thousand of inches, anything will have influence, you probably pay extra for the high technology used in the 2 invisible screws... lol Cheers, Pierre

[@ChrisB257]

Hey Pierre, Haha yes - dumbo here hadn't even noticed the missing 2 screws until someone pointed it out - duh! The unit certainly ain't bad considering price.

[@MrFlashx1]

Hi, did you remove the two screws from the front or were they missing when you got it?

[@ChrisB257]

Hi - this old fella totally hadn't noticed those 2 screws missing!! You and others saw it though :)

[@CompEdgeX2013]

Some of the import stuff is more than adequate for the home shop. Great deal for the money. The difference comes in the build quality... EG: yours is missing 2 screws from the bezel. ;-)

[@ChrisB257]

Hi Colin - yes, pretty adequate. Dang it - never even noticed the two screws missing!

[@barrycass2820]

Maybe the different pictures are that of the years. You know the improvement that’s probably old stock that didn’t sell.

[@ChrisB257]

Thanks Barry - you could well be right.

[@Daledavispratt]

It's mic enough for me! I sure hope you are feeling better, Chris! :-)

[@ChrisB257]

Hi Dale - very suitable at that price for a home shop. Quite a bit better now thanks - just a bit of residual now and again. This flu season has turned out to be nasty.

[@Daledavispratt]

I'm happy to hear that..it's a stubborn strain of flu, for sure.

[@453421abcdefg12345]

I think this is a very good workshop mic for every day use, at the price it is outstanding value, and with the very large display it would be useable in low light conditions, I would always run a sheet of paper across the anvils before I test a thing like this,(which you probably have done off camera), as when you are starting to go down to tenths even a grease smear can make a difference, one thing you did not mention, is it auto power off ? Or does it just lay there using battery life ? My Mitituro was £350 ,20 years ago, so this is almost a throw away price ! Chris B.

[@ChrisB257]

Hi Chris, I did clean the anvils first yes. I actually left it on unintentionally and it was not auto power off. No big deal for me but might be wanted by some folks. Certainly the price is hard to beat. :)

[@MaturePatriot]

Definitely made for a right hander. - I keep a set of visual cheaters in the shop to see those tiny lines. Old Eyes. - When I was in HS Machine Shop our tolerances were plus or minus 3 thou. Tenths were a pipe dream. - Chris, do want to work with me at 2bustedthumbs productions. LOLOL - The mic looks like it would work for me, I'm not building nuclear triggers. Plus or minus 1 or 2 thou will normally work for anything I do. Does it come with a calibration standard? - Great tool review video.

[@ChrisB257]

Hi, Didn't come with a cal std. Haha - yes, I'll sign up for the ''busted thumbs" LOL. I do still like analog and invariably use a head band cheater deal. Even though I had my cataracts done - close up is still a bit of a challenge.

[@EverettsWorkshop]

I'm actually pretty impressed by how close it was for the price, it should be quite useful for you. Couldn't help but notice your blackened thumbnail, that must have really hurt!

[@ChrisB257]

Hi Everett - indeed, price does represent pretty good value. The nail - that was an argument with my truck door back in October! Now I have the technicolor nail for probably 6 months!

[@MegaCountach]

Good video Chris, have you seen the "digital speed mics" from Igaging? They look interesting as they have a quick release lever built in to speed up measuring. I am still trying to decide if they would be worth the extra $ compared to the Bangood you have just reviewed. Cheers, Doug

[@ChrisB257]

Thanks Doug. Haven't seen the speed mics must admit... just looked that up. Seems the IP65 at MSRP of $240 is listed as available for $110 in round figures. Must say this spring loaded idea seems very handy indeed. I guess at that price (on the Igaging site) worth consideration. I'd certainly like that idea in use but must admit I still like an analog scale as well. Doesn't take too long to change setting using the "rolling hand" approach even though that takes time. So - as the saying goes - "you pays your money and takes your choice"! If I had cash to spare i must say I'd like to have one!

[@MegaCountach]

Hey Chris, sorry I somehow missed your reply. Yes, I figured you would be more of an old school guy (lol). I have Igaging X/Y DRO's I installed on my mill, and also their 12" height gauge, 4" caliper, 6"caliper (the digital ones) and really like them. On one of the DRO's the factory decided not to install one of the mounting nuts inside the LCD reader and I had to perform surgery on it and find another nut for it, luckily I found one in my shop... what a pain! I have read that Igaging customer service can be difficult to reach at times, but I have never contacted them myself. Keep up the great videos Chris Happy Trails, Doug Vancouver Island, BC

[@ChrisB257]

Hi Doug, Thanks. Sounds like the Igaging stuff is pretty good. My mill DRO scales and simple display were from Warco in UK - they are adequate at a fair price. Hope your winter in BC is manageable - been brutal down here in PAS.

[@istvanmeissler2238]

I have nothing against these micrometers, they can be adaquate and the cheap ones are now coming with larger displays which I like. My problem with them is that I think they are a bit over priced for what they are and also in comparison to what you can buy on EBay. I have purchased used but excellent condition Mitutoyo digital micrometers for this price or less. More than once. If this was 25.00 then I would consider it a buy. Not at 53.00. I have a Chinese digital caliper with a big display I bought for less than 20.00. It works well enough for a caliper and I love the big display.

[@ChrisB257]

I guess the thing is here - the comparison between a price-for-new as against a second hand good brand. Very often a used unit can be excellent value of course... and may well be the way to go sometimes.

[@istvanmeissler2238]

Yes of course you are correct. When I buy used, I aim for a known good brand and one which seems to be in excellent (barely used) condition. So far I have been very fortunate. I enjoy your videos and look forward to more in the future. Where in the world do live friend?

[@ChrisB257]

Thanks - hope to resume some videos before too long. I live in Pennsylvania U.S.A.

[@coldformer1]

i have 30 year old mitutoyo digitals that sill work will this still be working in 30 years?

[@ChrisB257]

Hi Jerry, You have a quality item there - should outlast you! :)

[@allannoyes4560]

Seems to be a adequate micrometer. You share the same injury with Mr. Pete a smashed right thumb I feel Your pain, how did it happen?

[@ChrisB257]

Hi Allan, Yes, pretty good value for the price. The thumb! Had an argument with the truck door last October - the door won! :) Pain went quite quick but now weeks and weeks waiting for the darned nail to grow out.

[@MrMa1981]

I have always to clean up the anvils with paper before setup 0 in a microns mike (50 millionth), and every single gage block measureament for. I am the only one?

[@chrisstephens6673]

No.

[@ChrisB257]

I did clean before hand yes. :)

[@MrMa1981]

I mean, every single measurements. Consecutevely.

[@pierresgarage2687]

To get the ultra precise reading, you're right, it doesn't takt much when you're a the fraction of a thousand resolution... A finger print is quite thicker than one could imagine...

[@derwissenskiosk8041]

Thats quite good value for the money i think... :D

[@ChrisB257]

Hi - yes, pretty good price I think most would agree.

[@rupert5390]

These things are rubbish -it will crap itself sooner than you think - spend the money on a decent one - do you guys expect these things to read wrong out of the box do you?

[@caseykelso1]

Gez 13 rubbish ? lol thats funny

[@caseykelso1]

and true
