I purchased this almost 2 years ago for personal engineering projects. So far, I think it is a great product that exceeds the price. This feels almost exactly like the ones I used during the same time period in my engineering classes, but these are a fraction of the cost. It contains all the features that you need, such as measuring inside diameter, measuring length/outside diameter, changing units, zeroing the scale, etc. The digital screen is easy to read. Each measurement is highly accurate, with a tolerance of 0.001" according to the manufacturer. My only problem I experienced is the included batteries are weak. It does include a replacement, but regardless it is a frustrating process to change the batteries. Regardless of this, the digital caliper exceeds expectations at this price and I would buy it again.

Great caliper at a better price. Seems accurate and sturdy enough to not have to worry about breaking it easily. The on/off buttons trigger easily, so these have a tendency to run down batteries quickly. But the batteries are cheap to replace. Easy to use, easy to convert to metric/standard. Easy to read display as well. Read more
After I ordered this Jiavarry caliper I read the one-star reviews where users complained it did not last very long for them before going into error mode and rapidly displaying random non-sensical numbers on the digital display. When it finally arrived (took a few more days than originally promised) I immediately tested it out with a 1-2-3 block that I purchased from Amazon for that purpose, as well as a feeler gauge set that I also purchased from Amazon. In both cases the measurement was PERFECT - the 1-2-3 block measurements were EXACTLY one-inch, two-inch, and three-inch all the way down to the thousanth (like 03.000, not 03.001 or 03.002). The feeler gauge I measured was also perfect (0.035 and so on) with no variation or skipping around with the measurement. We'll just have to see how long it lasts, but if it lasts 9-months or more, I will be satisfied given the low cost (about $15 with the discount offered by Amazon). It also feels substantial in weight, and well balanced, unlike the cheap Pittsburgh brand from Harbor Freight Tools which I've had for a number of years, but have never been as near as accurate as this one. The plastic case is also nice and should keep the caliper protected from the elements throughout its life. The only negative I have is the battery compartment has two very tiny screws holding a plastic plate over the battery, and I worry those screws could be easily dropped and lost. The screwdriver provided in the case is slightly magnetized so I'm hoping that is enough to keep hold of the screws. I imagine if I lose one of the screws I could use duct tape or something, but in the mean time I will just be really careful, hope the battery lasts a long time, and open the battery compartment with great care over a bench to keep the screws from scattering.

surprisingly good quality for the price. I have not compared the measurements with my older laboratory grade calipers, but I got this cheap one for my tool box anyway...and the case is very protective...nothing to write home about, and the cheap, molded plastic will not last long, but the case fits in a nice cubby in my box, so I am satisfied. one thing that shows it's lesser-than-professional build quality is how loose the adjustment wheel is. I had to check it was not about to fall off, but it simply has a lot more slop than a pro level. (this wheel is meant to spring away from the caliper so that you don't accidentally change the measurement.....standard mechanism....just a lot lower manufacturing tolerance at that point, so it feels loose...but works perfectly fine. Sure, this is an indicator of other build quality, but being that it is purely digital, with very course graduations, only the digital device and the track upon which it rides, along with those of the dynamic jaw, need be of excellent tolerance........WE WILL SEE.

I can't explain how excellent this is! Built like a tank! Accurate! Waterproof! Slide Lock screw! Enough batteries to last a lifetime! Case with screw driver! If you aren't sure trust this redneck and buy this caliper!! Unusually high quality for a great price! Smooth! Works perfectly! Easy to use! Large visible display! You will never need another! Sleek thin profile! Read more
I was so pleasantly surprised by the quality of this tool that I wanted to leave a review to give kudos to the seller/manufacturer. I was going to buy one of the dirt cheap models with plastic components and advertised ±0.2mm accuracy but I decided to spend a little more (even though nothing I'm currently measuring requires particularly close tolerances) and I'm very glad that I did. Right out of the box it feels like a professional tool and everything feel sturdy and robust. I agree with another reviewer about the adjustment wheel being a little "floaty" and I wish that it was a bit better engineered, but it doesn't affect the tool's functionality in any way. I used this tool to double-check some sizes before putting in an order for replacement components, and it confirmed exactly the measurements I expected to see. This is a tool I'll be happy to have in my kit, and it's definitely feels like a "buy it for life" product that won't need replacing for the foreseeable future. Read more
Useful caliper that is working well for me and was reasonably priced. Easy to use, accurate and well made. I like it. Read more
I bought this to use instead of a plastic body digital one. This caliper is stoutly built, highly readable display of in/frac-in/mm. Set screw, scrolling knob. Very pleased with my purchase. Comes with spare batteries and a screwdriver to remove the battery cover. Serviceable carrying case. Read more
