I was given this grinder two Christmases ago. I've used it daily on the fine setting. Others in the house have used it occasionally on the coarser settings. It worked until last month, when it wouldn't turn on. Taking it apart showed that the plastic hopper is mounted on top of a threaded, plastic pipe (which also forms upper edge against which the burr grinds). That pipe was cracked, and that prevented the hopper from seating fully on the two safety interlocks located on the top of the unit. We used it for a couple weeks by holding the hopper down by hand, but yesterday the pipe broke off completely (no great surprise there). I could hack it more deeply, but since the finest it could grind wasn't all that fine to begin with I'm going to go look for something nicer. Preferably something which grinds metal against metal, for starters.
