Kynup Digital Caliper, 12 Inch Caliper Measuring Tool with Stainless Steel, IP54 Splash Proof Protection Design, Large LCD Screen, Easy Switch from Inch Metric Fraction (300mm)

Item is as advertised. The all-metal caliper is very well constructed and robust. The LCD readout is large and easy to read. I find that the accuracy is excellent and the rolling wheel has a very smooth feel. The resolution is definitive and stable, not jittery or indecisive. It comes with a nice plastic protective case and two button cell batteries. This is one of the better digital micrometers that I have used. Excellent.

This is a one of those items you find a need for and don't know what to really trust. Junk rules supreme across the 'zon scape. Worry not. I was once in your shoes. This device is solid, feels really machined (doubt it it is but it has a solid heft and feel. I can always measure a cheap display from a good one by tapping it. Hollow sound, not so good. This one: solid. The measurements are accurate and you can switch between units easily. You also have a stop functionality for presets. Fantastic unit for the price. Highlyy recommend. Going to get a lot of use out of this.

My one complaint is that the storage box that comes with these calipers is truly terrible - it's made of super cheap plastic, and one of the latches completely broke after only being used about 10 times. But with that out of the way, these calipers are phenomenal, especially for the price. They open/close super smoothly, they come with not one but TWO extra batteries (and just the fact that they run on CR32 rather than watch batteries is a huge plus), they feel premium and durable without being uncomfortably heavy, and of course they work exactly as intended. I did a few tests to confirm their accuracy, and they passed with flying colors every time. These are really great budget-friendly calipers. Are they as good as the $400 Mitutoyo ones? Of course not. But if you're just looking for calipers for everyday use/hobbies (measuring things around the house, 3D printing, etc), these will get the job done effectively, and for only twenty bucks.

The display was already on when I opened the box but the power button has a definite 'click' to it so did I get a used one? It certainly doesn't look like it's been used and came with the manual, two cr2032 batteries and the screwdriver to replace the batteries with. First impression is that it's a bit heavier than my other caliper (202g vs 154g). It was displaying negative numbers instead of positive and the only to reset it was the take the battery out for a few seconds to 'reset' it. I like the fact that this takes cr2032 batteries instead of the less common lr44 in my other digital caliper. Be careful though, it's sharp! I was holding it too close to my face trying to measure something in the light and almost took my eye out. It's about 0.04 mm off from my other digital caliper but I'm not sure which one is more accurate... I purchased this one because my Neiko caliper kept resetting and displaying wildly inaccurate numbers if I went passed a few inches & because it uses a more common battery.

I picked these up for some 3D printing work and they ended up being way better than I expected at this price point. The measurements are consistent and accurate and switching between inches and millimeters is just one button press which is really convenient. The auto off feature is a lifesaver for battery life since I never remember to turn things off myself. Seriously a steal for what you get.

This caliper is awesome! I checked it with 1-2-3 block and it is perfect. Love that it has 3 modes: inch, mm, and inch fraction. The material quality seems great. Good value for the price. Minor nitpick is that the case feels cheap. In case you need further assurance on accuracy, checkout the comparison video by Project Farm on Youtube. One suggestion: when putting it away after use, I would recommend locking it at zero and then turning it off. Otherwise, even slight movement when putting it in the case could turn it on (as it turns on automatically when you try to measure something). It does have the auto turn-off feature so not a huge deal but if you put box in a drawer, then it could turn on due to vibration every time you open the drawer for any other reasons. Also, in case anyone doesn't know, these calipers (like most other) have 3 way of measurements: outside, inside and depth (using the tail end). Maybe more that I don't know yet.

So, I fully intend to keep this thing for a long time and use it for the odd job around the house. For that, this caliper is perfect. Measures far more precisely than I'll ever need. However, I actually bought this thing to measure my guitar strings. I had it set up over a year ago and the strings needed changed, but I had no idea which gauge they were and the setup is still great, so I wanted to get the same gauge strings to keep the setup intact. So I bought this, measured the strings. Exactly 0.010 on the high E and exactly 0.46 on the low E. Satisfied with my purchase. Other things I liked. 1. Comes with 2 spare batteries and a screwdriver to access to the battery panel. 2. Comes with a cheap, but functional plastic case, which I appreciate. 3. The instructions and buttons are clearly labeled and easy to read. In all, unless you need this for professional work, this is about as good as it gets. Weighty, feels good, works well, and it shined for the one thing I've used it for so far. Long term durability will be seen over time.

Has a great weight to it. Definitely not made cheaply. Not made out of plastic. Made from hardened stainless steel. Screen is easy to read. I like how it comes with 2 extra batteries. Show's fractions, mm and inches.

Upgraded from my old reliable analogue Vernier caliper scale as finding it harder to read as I get older. Can now get readings down to .01mm accuracy without eyestrain. Nice clear display readout, Auto off display to save battery. Seems well made and comes with spare batteries. Only negative so far is the Hard plastic case has no shaped foam insert to protect the device from rattling about inside

Simple, accurate, useful. Precisely measures my lapidary stones to precision enough to verify my grinds. Feels like solid quality. Good blue case, nice and sturdy.

qualitativ hochwertig, passt

Fácil de usar y si repite las medidas de lo mismo que mides aunque tarde un poco en dar el mismo valor, lo que mas me gusto es quen se prende solo cuando lo abres y te evitas precionar el boton de ON. Aunque para medir cuerdas de tornillo muy cortas y finas no es posible eria como de 1 mm en adelante

I always used cheap calipers that cost 15-20 euros and all had the same problems: they don't return to zero, so you have to zero it every time you take a measurement, they eat up the battery very quickly and they die after one year or so. I wanted something better and I came across the Kynup that had good reviews and I liked the large display. When I received it and opened the box I was pleasantly surprised - this calipers is heavy and build very well. It uses CR2032 batteries, so it should last for a long time. The machining on the jaws are perfect and you can't see any light shines through the Jaws when they are closed. The micro adjust wheel is very stiff and allow very small changes, unlike the cheap ones. The display is large and clear and has 1/100 of a millimeter resolution, and best of all - it always return to zero!
