Accurate and Reliable Digital Caliper
I am very happy with this digital caliper. It feels solid and well made and the measurements are accurate every time. The display is clear and easy to read and switching between metric and imperial units works instantly. The sliding action is smooth and the zero reset function is very handy. It comes ready to use right out of the box and feels professional for the price. Great value for anyone who needs precise measurements for DIY or technical work.

Dependable and accurate. What more do you want?
These are fantastic quality. I’ve had some others in the past. But these are accurate and more dependable. Wouldn’t hesitate to purchase again.

Seem robust and excellent quality.
I haven't used these properly yet but my first impressions are excellent. I'm replacing a cheap set with plastic jaws that used to kill the battery when left unused. These are supposed to 'cut' the power totally when turned off, thus you don't have to keep taking the battery out between uses. They are very robust and heavy. Feels like a quality item, I'm sure I'll get a lot of use out of these.

An absolute steal!
This seems to be a perfect caliper! I genuinley see no fault in it, it contains 2 spare batteries, a screwdriver for the battery cover AND a case to store it in. It has a strong feel to it whne you pick it up. I had another cheaper one that was made of plastic, i replaced it with this, the difference was crazy! The thing that i find the most insane is the price. i managed to pick this up for ~£16 but even the £20 normal price is an absolute steal. i would HIGHLY reccomend this from what i have experienced so far and it seems like it will stay durable.

Good quality precision instrument
Amazing piece of precision kit at a fantastic price. So useful around the workshop and even comes with spare batteries. Nicely weighted in stainless steel. Gone are my days of trying to guess fractions of a millimeter on a steel tape.

Cheap electronic caliper.
Cheap and not accurate past one place of decimal. HOWEVER for day to day workshop use checking drill and screw sizes etc it is fine. It is reasonably robustly constructed and does fractional sizes as well as the usual metric and imperial.

Well made
Very pleased with the digital display as it shows accurate readings within.001 inch. Having the metric choice too is helpful for an old imperial engineer such as l. The depth measurement facility is very useful. The stainless steel instrument is well made and good value.

Accurate, easy to read, and very handy for small measurements
I bought this Kynup digital caliper for general DIY and workshop use where I wanted quick, accurate measurements without guessing. It’s easy to use and the digital display is clear and readable, which makes measuring much faster than using a traditional vernier. Measurements feel consistent and accurate for typical tasks like checking thickness, diameters, and internal dimensions. Build quality is decent for the price. It feels solid enough for regular light use and hasn’t gone out of calibration or behaved unpredictably so far. Overall, a very practical measuring tool that’s useful to have around the workshop. Good value if you want accurate measurements without spending a lot.

Super pied à coulisse, entièrement en métal, ce qui lui donne un vrai ressenti de qualité dès la prise en main. La finition est propre, les glissières sont fluides et la précision est au rendez-vous (je l’ai comparé avec des pièces calibrées, aucun souci). L’écran est clair, la conversion mm/inch fonctionne très bien, et la remise à zéro est rapide. Idéal pour mesurer des pièces imprimées en 3D, du petit outillage ou pour l’atelier en général. Fourni avec une boîte de rangement rigide et une pile de rechange. Rien à redire pour le prix, c’est un excellent outil que je recommande sans hésiter.

Highly accurate, very reasonable price. I have tested this to be accurate down to the display's 0.01mm.

Dopo il primo uso mi è sembrato di ottima fattura con un materiale molto resistente, scorrimento regolabile e fluido ottimo sistema di bloccaggio... Rispetto al mio precedente calibro un deciso passo avanti.
