Kynup 6 inch Digital Vernier Caliper

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.

I h ave been pretty pleased with these. I have not attempted to check the accuracy, maybe I should. But they are easy to use, easy to zero and easy to move through the menu for different measurement units. Thanks goodness for the auto off. That helps with the battery life and I almost always forget to turn them off myself. The quality of the materials are pretty good. They feel solid endnote "cheap" The display is good sized and clear/clean. It is easy to read, and sharp details. Good value for the money. I am pleased with the purchase. I would r recommend and would also purchase again if needed.

This thing is heavy! Ours arrived with one button battery in place and two (2) spares! It seems to turn on as soon as you slide the display housing, a convenient feature but which may suggest why you need the spare batteries. I like that the reverse side has two legible thread charts for converting ISO to Imperial. It displays fractional inches! I cannot attest to its precision but it's good enough for my projects. It comes with a nice case and mini Phillips driver to remove the battery cover screws. Other reviewers suggest short battery life and erratic display behaviors. I haven't had it long enough to experience these but will be on the alert.

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.

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.

I’m sure like many purchasing calipers in this price range, I don’t use them often and don’t have a need for 100% accuracy. If they measure reliably and continue to work the next time I need them, that is all I really need. Previously I have purchased multiple Harbor Freight Pittsburg brand calipers which met my needs during initial uses but tended to stop working for unknown reasons when I went to use them 4 months later. The last set of Pittsburg calipers I had, I stored inside a range bag which got wet from minor rain on the outside of my range bag and that slight moisture which minorly transferred to inside the bag stopped them from working. I got these Kynup calipers due to the IP57 rating. My initial impression is they are a much higher build quality than the Pittsburg Calipers with more features, smoother operation and a stronger storage case, all at the same price. If they last due to being moisture resistant unlike the Pittsburgs, I will be thrilled and will update my review and purchase more of these Kynup brand.

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 loved this caliper the moment I got it. Heavy, which in my mindset means good, precise measurements and the fraction display is awesome. Comes with two replacement batteries. Totally recommended.
