I actually purchased these for a guy at work because he liked the tubular mics I bought for myself on amazon about a month prior. Even though they are cheap, the quality is still good for what you're paying.

I am a professional machinist with over 10yrs on the job. These are just as accurate as my Starrett ID mics. The tube size can make it a little awkward depending on the feature you are measuring.
