Kynup Digital Caliper Measuring Tool, 12 Inch Stainless Steel Micrometer

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.

This vernier caliper is very well made and equals the quality of ones made by more well known precision instrument/tool makers. The one feature I like most about this tool is the thumb wheel that allows the user to make extremely fine adjustments to what ever it is they are measuring. The clear digital read out in millimeters, inches and the ability to switch between them and an added fractional read out is buy far one of the best features of this instrument. There is also a depth gauge feature as well. Well made, feature rich and an extremely low price make this one an awesome buy.

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 am more than satisfied for the price. I expected no batteries. It came with one in it, and 2 spare. Most people will never have to buy one for it. And it is very accurate, most of the time spot on. Worst I got was off by .02mm. Close it and zero out, was fixed everytime. Measure twice, it will be exact

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.

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.

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.

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.

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

The battery contacts of my previous (6", run-of-the-mill, black plastic, red-green-blue buttons, LR44 battery) digital calipers were heavily corroded which made them work erratically. This breaks the entire tool, as the analog scale of these digital calipers is unusable. So I set out for a new pair of calipers. My use is in electronics and PCB design, to measure component pitch, PCB sizes and the like. So no need for high, multi-decimal precision, but a mm / inch conversion is nice to have. And 200mm / 8" comes in handy every now and then when measuring larger enclosures. Initially I was looking for a pair of calipers from an 'A' brand, but for my use their prices, especially for the 200mm ones with some IP protection, were just too high. So I searched some more and stumbled on these Kynup calipers. It promises IP54, which made me think the battery terminals might fare better than these in my previous pair. It shows mm and inches, and fractions as well. And it is 200mm / 8" long. In short, it ticked all my boxes for €40.-, so I ordered a pair. Amazon got them to me in 2 days and I have to say that I am pleasantly surprised. Apart from looking and performing exactly as advertised they also have some extra features I like: - They are completely made out of metal. Buttons, battery door, everything but the display window. - The battery door has an o-ring for protection against fluids. - They have auto-off. That feature will save me a lot of batteries. - Even more nice, they have auto-on. Just move the jaw to measure something will switch them on. - They run on CR2032, which I have more of lying around than the smaller batteries used in other offerings. I read some reviews where people complained that the decimals are smaller which makes them harder to read; that is indeed the case, on the other hand the fact that these decimals are separated by their size makes measurements easier to interpret, at least for me. The tool is a little 'coarse' to the feel; corners and sides are a bit sharper than with my 'A' brand non-digital calipers. This however is no big deal. You ain't going to cut yourselves on them :-) All in all I find them a lot better than the non 'A' brand digital calipers they replaced and at less then half the money. Obviously I cannot say anything yet about battery life or the tool's longevity, but if the electronics do not fail I have good hopes these calipers will last into my retirement.

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!

Imposible pedir más por menos, buenísima calidad
