These calipers are definitely of high quality and work as expected. The only downside is that they don't turn off when not in use. Or, if they do, it will take so long I couldn't witness it. I've left it on too long several times only to return to my desk to see it's still on. It's just not typical of some of the other calipers I've used. In terms of what it needs to do - it's great!
