My previous coffee grinder was a Chicago air grinder and the bearings wore out too quickly. This blue, on the other hand, is chic. It is bulky and has a certain weight. It won't stop or slow down no matter how hard I squeeze it. And it has a rear exhaust and a floating end where the plug goes in, so that's pretty cute. There are no real disadvantages so far, except that the recoil really makes the hand fly.
