I was concerned that such a cheap instrument wouldn't be strong or have problems because I was measuring a rotating assembly. It was great to see that it lasted as long as the commercial devices I used at work and performed the same. If you have used it before, it is exactly the same as the good ones that are much more expensive. I had no problems and did everything right the first time. And I always double and triple check things, and it's been very consistent. I'm very happy, even though I might not need it for a while, it's nice to know I have a good tool in my tool arsenal!
