I haven’t actually been able to test my caliper to give it a proper review because it came with a dead battery. When I tried to replace the battery by following the instructions the cover wouldn’t budge. If you look that the picture of the instructions on how to replace the battery, it indicates to slide the cover in the direction indicated. First, there’s no arrow indicating any direction to slide. So using common sense, i tried to slide the cover to the right first, and when that didn’t work, up and to the right. Still nothing happened. I saw a tab under the cover and thought maybe it was a locking tab which had to be depressed before allowing the cover to slide out. Used a small screwdriver and pushed down on the tab only to make a dent in the tab and scratch the cover.Thankfully someone else had this problem and asked on Amazon. The secret is that there’s a screw on the backside holding the cover which must be removed before you can LIFT (not ”slide”) the cover off.I sent the first one back because I couldn’t figured it out the first time and thought it was defective.Update the instructions and I’m sure fewer people will return the product.Now that it actually works, I can test it and update my review based on the functionality and accuracy of the caliper…

As manager of a phone repair shop and a student of drafting, my son was super excited to get this as a Christmas present. He said it was perfect for his needs.

They appear to be a quality caliper. Feel heavy in the hand and have an easy to read display.BUT, they did not work when I received them and it was problematic to find and open the battery compartment.Problem solved: The battery that came with the calipers was DEAD. Luckily, they came with a second battery?? Maybe that is a common problem so they ship with a 2nd battery.

The battery died in a month; however, a spare battery is provided. Batteries draining is expected with calipers, even when off. The jaws do not glide smoothly like a Mitutoyo; however, it is way cheaper and works well.

The battery was dead when it arrived, luckily it came with a couple replacements, though I would assume it has something to do with the loose fit in the case, as when I wiggle it back and forth inside the case it turns on sometimes I would assume that is what lead to the battery inside being dead upon delivery.Other than that, it requires a lot of closing and taring as it seems to be off .01 - .02mm just from opening/closing. So if you don't need super precise measurements it's probably fine. The thumbscrew is also extremely loose, which is pretty annoying, but all in all it's not the worst digital caliper I've used.

So far I'm liking them a lot. I've been able to make same pretty percise parts with them in fusion doing 3d printing. I gave it a 4 for precision only cause I did have to set them to zero a few times but overall they seem to work very well.

Interesting my updated negative review got censored. (Short version: The accuracy variance disclosed is the LEAST amount of variance I can get out of it.. It gets Much worse the larger the measurement... and random who knows what.), But I have a third update. There are 2 micro screws on the top that can adjust how tight the control box hugs the caliper. I tightened mine so that it had drag.. then backed off a hair.. and now they are performing like they should. Without fixing them though .. they were pretty inaccurate.2nd review: denied. censored.. Ahh yes I think I know why... well I don't know how to tell you guys about what goes on here without getting censored. incredible times. Just this line here probably gives it a 50/50 it will get through now. You censors are salt of the earth for sure. Just wonderful human beings. Sainthoods for you. I like strawberry flavored shoe polish please.first review: So far they are perfect. Long term I will have to come back to this review. At first I thought they did not turn off by themselves to save the battery, unless I clicked them off.. but I was wrong and they raised me one. They come ON just using them. No need to ever turn on or off, which somehow feels like more luxury than I would have thought. I saw them on and thought oh great, more crap lol.. but they had just turned on right in that moment. Very heavy which surprised me. One more decimal than my last ones. plus the plunger thing. plus the fine tune wheel. plus metal. Consistently go back to zero. Seem pretty darn good for anyone but space-x.

Very happy with this set of calipers. I tested on a name brand gauge block and it was right on the money. I also appreciated that it came with a battery in it as well as a replacement battery.
