  • So useful and a great value!
Model: KY-21B
I keep finding more uses for this and it has already saved me more than it cost because I have less rework to do and I'm just a hobbyist. It's very easy to use, basically just turn it on, zero it, and adjust it to match what you're doing--internal measurement, external measurement, and a surprisingly-useful depth measurement thing on the end. It comes with a protective case that is quite substantial and I put it back in there after every use to protect it from other things in my garage-based shop. I've used it to find the depth of slots cut in wood, thickness of wood (very useful to decide if routed molding is good enough rather than by one's own eye), make reproducible measurements (because it shows you digitally and not by you trying to judge little lines). It has both inches and metric, which is important if you're trying to measure existing screws and bolts--I can just put it up there and check both measurement systems, and the one that gives a typical size number is the kind it is! It can give you a rough idea of board thickness, which is especially important if you just tinker and don't have a thickness planer, at least you know which pieces will work pretty well. The buttons press crisply--just enough resistance so you know you pushed them and they pop right back up. The display is very readable, and for the physical lines, I would recommend the white on black even though it was a little more because it's readable at different angles and different lighting. Something I tested was reproducibility of results, measuring things and then shutting it off and on and trying again--no problems there. Great for judging thicknesses of model-making metal strips and things like that because it's hard to tell by eye but this just puts a decimal number on it and I can compare them easily. Still finding new things to do with it, which makes it a kind of MVP as tools go. ... show more

  • Great so far (Made in China)
Model: KY-21B
I never knew how much I needed a set of calipers until I got this. So nice. It's weird because they are made in China and I use them to fix other cheap Chinese trash products sold on Amazon. Hopefully these will be the first Chinese product that doesn't break within 6 months. I assume it's accurate but you know what they say about assuming... ... show more

  • Perfect height balance, thanks to these
Model: KY-21B
I needed these to make sure when I lowered/raised my suspension height in my mustang that both the driver and passenger side would be PRECISELY even, They worked perfectly, easy to use, didint fall apart, keep in mind I’ve only had it for a couple days, we’ll see how it weathers the sands of time

  • Really nice for the price.
Model: KY-21B
Really nice for the price. Got the version with the black scale. Easy to read. Checked calibration against a 120 Dial caliper. Pretty much dead on, within the .0005" which is as accurate as the scope of work I'm doing requires. There is a slight wiggle between jaws but at this price point that can be overlooked. Can't speak to longevity but if I needed a second one at this time, Yeah, I'd buy another one. ... show more

  • Kynup digital calipers
Model: KY-21S
Kynup digital calipers The calipers are of good quality and have repeatedly measurements if I have any complaints it would be the fraction measuring 1/128 inch my mind doesn’t seem to work past 1/64 inch but that is just me. Overall I recommend.

  • Sturdy stainless steel
Model: KY-21S
Sturdy stainless steel. They have a little weight to them. I bought them to measure roller bearings for a repair project. I'm happy.
