I bought this (4400-0010) for CNC use for my hobby as I don't have the budget to buy a much more expensive indicator. I figured it would be a reasonable alternative to a Mitutoyo. It seems to work as intended, but I didn't install it with 7/32" and 1/4" shanks as advertised. Instead, it came with 5/32" and 3/8" stems. I am contacting the seller to see if this issue can be resolved as I would rather have the advertised stems. If this works I will update this review.
