Kynup IP67 Digital Caliper

Great quality, nice case, backup batteries included. Very impressed with precision and overall quality for price

I make accessories for commercial products. Being able to accurately measure those products is key to me getting the prototype design right the first time around. These calipers are both inexpensive and accurate. Certainly accurate enough for the work I do.The construction is solid and the pointed parts are SHARP so be careful! Comes with a user manual a small screw driver to open the battery compartment AND two extra batteries.Only nice thing to have would be a backlit LED display but that's more of a nice-to-have rather than a requirement.

I purchased these in April of 2023. I’ve used them a few times, and they worked great. I’ve taken very good care of them. They are kept in the bag in the case. They were never dropped or mishandled and they were working when I put them away. This morning they’re dead. I changed the battery per the instructions and they’re dead. If it’s any consolation they went peacefully while they slept. Too bad, I really liked them.Amended 06/24/24: I sent a message to the seller and let them know about the problem. They answered right back and offered to send me a new one despite being beyond the warranty. I’m pretty happy with their customer service. Hopefully the new one will last.

Arrived same day, exactly as described by Amazon. Excellent fit and finish. Easy to use, select units and very easy to read repeatable results. Even includes two extra batteries in the plastic (a bit on the flimsy side) case. Really great value.

Got these to do measurements for car repairs. They are very easy to use and seem very accurate. I like that they can measure inside and outside dimensions.

I like ease to read display and smooth operation. Nice case and extra battery.

Nice set of calibers well made and accurate I would buy again

I purchased two of these measuring tools. The build quality appears to be very good. I did not yet get to use them for my work. I tested them on some pieces that I know the measurements. The accuracy is good. I gave this instrument 5 stars because for its price point and its actual accuracy. I found it to be very acceptable. It has a good quality feel to it.I have seen in some reviews with some of these the measurement may not be consistent. There are factors involved such as the acceptable tolerance of the instrument, how even you place the calipers, how much pressure you exert when adjusting the calipers against the surface to be measured, and the temperature of the item to be measured. For general type of work this instrument accuracy is very acceptable. For all materials there is thermal coefficients to be considered when making precise measurements. This factor depends on the type of material to be measured.In relation to the cost of this instrument the precision is impressive. From my perspective it is very acceptable for home, and work projects. I will be using it for measuring fittings, electronic wire diameter, thickness of electrical conductors, and etc.--For example to calculate the coefficient of steel:Multiply the temperature change by 7.2 x 10-6, which is the expansion coefficient for steel. Continuing the example, you would multiply 0.0000072 by 5 to get 0.000036. Multiply the product of the expansion coefficient and the temperature increase by the original length of the steel. The coefficient of thermal expansion for steel is 0.00000645in/in/deg F.With this hand held instrument environmental temperature will also have some affect on it. This is normal.

Nice bit of kit, fairly well made and accurate. Might not last too long in a busy workshop environment but perfect for occasional use. Comes with 2 spare batteries which is generous.

Veramente ottimo calibro, robusto veramente ben fatto, in lega non plastica, consigliato.

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

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