Quite impressed with the value and quality of the product, especially for the fair price! The calipers are sturdy, the adjustment wheel is smooth and firm, the measurements are accurate, and the hold screw keeps your measurement type! It was certainly a change from my previous plastic cheapo, plastic calipers, but I wish that I would've done it sometime ago! These were an incredible step up, and only a small jump in price! The functionality is excellent, keeping your measurements, precise, and easy to use! The product comes cleanly wrapped in a nice box with a sturdy, hard plastic travel, and storage case! They look and feel expensive, while functioning like an expensive set also!

This is a very well made, high quality and accurate tool. All metal (except plastic screen), solid weight, balance, slide action and feel, very precise and the lock thumb screw is handy too. I purchased a caliper from the TikTok store that turned out to be plastic, not very precise, and the electronics and display went spastic after a few months (gibberish and wouldn’t turn off except by removing the battery). This is a great tool for a great price. Highly recommended!

Nice tool. Accurate--fortunately. Was nervous about the precision, but is working out so far. Comes in a budget, vacuum-formed case that is reasonable for the item's price and build quality (certainly acceptable). Even comes with batteries. 👍 Does it deserve consideration? If you are not building surgical equipment or a rocket ship to Mars, then, yes. Serves most needs of reasonable scope and precsion. It is a decent product at a decent price.

Best affordable digital calipers you can buy. No need to look any further. They are pretty spot on and they feel like quality. Full time mechanic and part time hobby machinist here for what it's worth.

I have to say that these calipers far exceeded my expectations. I thought for sure that they would be made with a lot of plastic parts even though the description sain stainless steel. I was wrong about that. I really like the way the battery cover is screwed on, they even supply a little screwdriver and 2 extra batteries. I took the cover off to install the batteries and there were batteries in it already. The only issue I had was that I didn't have my glasses with my and the screws are so small it was hard to see 🙃 I checked the calibration with my micrometer and they were spit on. I ordered 2 because of the price and the fact that I seem to temporarily misplaced my tools quite often.
