Nothing to write home about
I love everything about this little tool - it's lightweight, compact, has everything you need to tune your board and whatever else you may have lying around - but the one complaint I have is that the little ball bearing that is under the metal band likes to pop out. Do you know how hard it is to find one of those suckers?! Luckily I've lost it only while inside and have managed to hang on to it. It's necessary to have in order to hold the bits in place. Other than that, it's solid.
