Overall the kit seems decent. I do take a bit of issue with the claim that this can work at any angle. Ultimately there's a bounce that this is measuring and pretending like the direction of a gravitational force isn't going to have any sort of effect is pretty silly. Might just be a skill issue with me being new to the tool, but time will tell.

The page describes that it is Equipped with 7 types of impact devices which need not to be re-calibrated when changing them, but then the kit is delivered with only one type and it does not state how to get the remaining 6 types. Pretty disappointing

After reading the other review I was super nervous about getting this because I thought it might not come with the parts it was supposed to. But ours did come with all seven. Everything came very well packed and secured and was in pristine condition! The instruction manual was clear and easy to read. My husband is super familiar with using these so he knew exactly what to do. Everything functions as it supposed to and it's very accurate as well! Definitely a great value for your money. And a solid 10 out of 10

This portable hardness tester that my boss bought for me is really great! I was pleasantly surprised from the moment I unboxed it to the moment I used it. The material is very good, the feel is comfortable, and the functions are also very powerful. I especially like its portable design, which is convenient to carry around. It is extremely cost-effective and is definitely worth buying!

This product is made of high quality and works great!
