Nicely made. So far they've worked great for my needs, which is to measure gaps in woodworking projects to fix issues.

  • Good quality!!!
Everything seems to function properly! I used a micrometer to check some of the most used ones and the thickness and accuracy was spot on. They appear to be made of good materials so they should last a while. The valve adjustment was a lot easier to use. The only problem I have is the holding screw on the end doesn't seem stay tight. I can do a work around on that so I would buy again. ... show more
