Kynup Digital Caliper 150mm, Stainless Steel Electronic Vernier Calipers with Large LCD, Precision Measuring Tool, Inch/Millimeter/Fraction Conversion, Auto-Off Function(6 Inch)

I bought the Kynup Digital Caliper for a few precision jobs around the workshop — mostly for woodworking and model builds — and I’ve been thoroughly impressed with it. For the price, it’s easily one of the best bits of measuring kit I’ve used in a while. The build quality is surprisingly solid. It’s made from stainless steel and feels reassuringly sturdy in the hand without being overly heavy. The slide movement is smooth and precise, and it holds its position nicely once you set it, so you’re not having to re-zero or second guess your readings. The large LCD screen is one of the standout features. It’s bright, easy to read, and gives results instantly in either mm, inches or fractions — a simple button press lets you switch units depending on what you need. As someone who works with both metric and imperial depending on the job, this flexibility is a big plus. Accuracy-wise, it’s been spot on. I’ve checked it against known reference objects and it’s come in dead accurate every time. The ability to zero the measurement at any point is also really handy when doing step measurements or internal comparisons. One small detail I really liked is the auto-off function. It saves battery life by shutting off when not in use, but switches back on quickly when you move it again. You also get a spare battery included, which is a thoughtful touch and something a lot of manufacturers overlook. It also comes with a durable plastic case that keeps the caliper protected and clean when not in use. Everything fits in snugly and it’s easy to store on a shelf or in a toolbox. Only small niggle is that it’s not waterproof, so you’ll want to avoid using it in damp or very dusty environments. That said, for general use it’s brilliant, and with a bit of care it’ll last for years. In summary, the Kynup Digital Caliper punches well above its weight. Accurate, reliable, easy to use and a great value tool that’s ideal for hobbyists, engineers, woodworkers or anyone needing precise measurements. Highly recommended!

Really pleased with this purchase. I find it invaluable for my hobby which requires precise measurements of diameters of turned metal bars. Product feels top quality, extremely accurate, automatically turns itself off after inactivity to save battery life. The carry case is a nice touch too, and all for a reasonable price.

Well, on opening the cardboard sleeve and it’s blue plastic vacuum formed box you get to see it looking beautiful and shiny. There’s a couple of spare batteries, instruction manual, calliper tool and even a little screwdriver to be able to change the batteries with. The unit actually came with batteries in it which is great and providing a spare set is even better. I went for the slightly more expensive metal version as apposed to the cheaper plastic jawed one because I like to buy things that will hopefully last longer. Instruction manual is good, although it is pretty easy to understand, you can change the measuring unit via a little button, lock the device via a little top screw and it’s easy to operate the device for external, internal, depth measurements. Display was clear and easy to read and comes with off button to save its batteries. Instruction manual had a couple of mistakes in it, mentioned the locking screw was number 3 on the diagram and it’s actually number 2, (3 is the lcd display) and then also says to reset the unit by taking out the battery and it resets after 30 “secretary” which I presume should be “seconds” So it lost a star because of those mistakes, it’s the details that count. Unit feels well made, no issues with working it and hopefully it will serve us well for years to come.

Really impressed with this caliper. The screen is big and easy to read, the buttons feel decent, and the measurements have been spot‑on for my prints and small hardware checks. Swapping between mm and inches is instant, and it zeroes cleanly without fuss. It’s not a premium metal‑body tool, but for everyday use it’s accurate, reliable, and way better than I expected at this price.

The item is of a good quality, and is easy to use. It comes in a plastic case for storage. It is obvious that it's carbon fibre due to the weight. Carbon fibre may not last as long as a steel tool but for the price (below £9.00) it's very good value for money. I would recommend this product.

I wanted a replacement for my old vernier calipers as I'm getting old and its difficult to see the scale so I thought I would give these digital ones a try. So pleased I did as not only are they very accurate, the display is very easy to read. To check the accuratey I got my trusty feeler gauge out and, after checking some of the gauges with both my old vernier calipers as well as my micrometer to verify the sizes were correct I gave these new ones a try. And they were bang on.. well within their stated tolerances. See my video showing the 0.28mm gauge. It was difficult to film one handed but you can see this new digital vernier caliper measured it correctly. (I did test more but did not film and it was accurate on all of them) They are very well made and feel substantial in the hand. Come if a protective plastic case with a couple of spare batteries. Even has a conversion scale on thr back of them. All in all.. a very precise tool for relatively little money. Very happy with them.

If you're looking to get an accurate reading of "Is it closer to 1.5mm or 2mm" then these are fine. If you need even the advertised precision of 0.2mm+- then I would look elsewhere, these are always -0.1 to -0.3 when I put them back to 0 so they are not keeping their zero correctly. For £10? Sure whatever, if I stood on them and broke them I would even be mad.

Good product . Does the job nicely.

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

Die Schiebelehre ist für den Preis mehr als okay. Ist gut verarbeitet und sehr genau. Sie kommt in einer Kunststoffverpackung und ist daher auch schnell aufgeräumt und kann nicht kaputt gehen. Hatte vorher eine andere diese war aber leider sehr ungenau und von der Qualität kein Vergleich zu dieser. Ich kann sie mit gutem Gewissen weiterempfehlen und würde mich über einen Klick auf "nützlich" freuen

I like this 150mm (6") stainless steel Kynup Digital Caliper. Perfect length for 95% of my needs. The fraction option is a nice touch. It is well built and has a nice weight to it. The slider wheel works well and the main part has ridges in all the right places in order to move it back and forth with ease. I did my research and this caliper was the best price and quality for my buck. I am very happy with my purchase and would recommend it. I paid $29.74 id Nov 2025. Cheers Gary

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.

Delivered as described. Solid, robust, 2 spare batteries, accuracy in spec limits 0.02mm.
