This wrench is well made and has a nice grip. It can be adjusted, which comes in handy if you have a lot of different sized coffee grinders (probably). I have a grinder and would prefer a fixed sized wrench which can be had for less. The problem (as I understand it) with the adjustment is that only one of the teeth moves to the right or left. Have no other. If it was more like a wrench it would work much better.
