Fantastic purchase!
Woah! For less than 16$ these are of amazing quality! Super accurate and don’t need to be zeroed after every use and will save the measurements after powered off and back on.The display is very crisp and clear easy to read as most digital calipers are.They feel very weighty and durable and the locking screw has better hold than I’ve ever felt on a pair of calipers.Highly recommend if your looking for good calipers at in this case a very cheap price.100% would purchase again but I don’t think I’ll ever have to!also comes with three batteries!

The Most Useful Tool I Did Not Know I Needed
I have only had this digital caliper for several days, but I can already tell it is one of those tools you end up reaching for all the time. The first thing that stands out is the build quality. The stainless steel body feels solid and smooth when you slide it open and closed. There is no wobble. No cheap plastic feel. It glides with precision and locks down firmly when you need a steady measurement. The large LCD screen is clear and easy to read. Numbers show up instantly. Switching between inches, metric, and fractions is simple and quick. That feature alone makes it incredibly practical whether you are working on home projects, automotive parts, 3D printing, woodworking, or anything that requires accurate measurements. Zeroing it out takes one tap. Measurements are consistent and repeatable. Inside measurements, outside measurements, depth readings. It handles all of it without guesswork. If you care about accuracy, this gives you confidence right away. For the price, it feels like a professional level tool without the professional level cost. It is one of those purchases that makes you wonder why you did not buy it sooner. If you do any DIY work, home projects, or detail oriented tasks, this is a tool you will be glad you have. Even after just a few days, I can confidently say it is perfect for what most people need.

Surprisingly good quality for an el-cheapo caliper for my toolbox
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.

ADRIO Digital Caliper- Quality at a budget price
Caliper appears to be well made, finish is good, activation buttons (power, mode and zero) operate smoothly. Unit comes with batteries installed plus extra batteries, and the case includes a jeweler's screwdriver to remove the tiny screws on the battery case. I purchased these for a bike shop, opting to pay slightly more than the cheapest version at Harbor Freight to gain accuracy (bicycle parts are often measured in tenths of a millimeter, so a fair degree of accuracy matters). Case is plastic but appears to be sturdy enough to protect the instrument adequately. Delivery was delayed slightly but I still got the items the next day following ordering.

Good Tool
Awesome tool. This will get the job done. Pretty accurate, easy to use. It’s definitely worth the money. The moving wheel is a little loose but I think it might be fixable if I can figure out where to tighten it maybe.

Extremely accurate, well weighted, impressive caliper
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.

Not perfect but well worth the price for light/amateur use. As with most digital calipers, the problem is getting it to return to "000" when closed every time. I often have to re-zero when I close the jaws. This is not a reason to avoid buying - just something to be aware of. I've owned the hugely expensive Mitutuyo equivalent and even this had the same problem after some time. The battery cover secured with two M2 screws (not self tappers) instead of the flimsy sliding plastic lid on other models is a nice touch.

This is my first proper digital caliper, it felt solid in the hand as most steel do, it slides smoothly, it measures a accurately, these are the good parts. But is the maker expecting us to always wear a protective glove in order to use it? Cause if you don't, you'll get cuts and scratches by the sharp edges everywhere! I'm not talking about the pointy measuring corners, but all other edges, only the long slider parts are sand smoothly. I had to spent minutes to use sandpaper to protect myself. This show that a product may be good at performing its task, the user experience is what make it used frequently or just thrash one side. Also, the rolling wheel is so loose it sound like a bell when carrying around, no backlight. I do not recommend buying this, get something from brand name that treasure their reputation instead of some unknown that change its name when the rating gets bad.
