I thought I couldn't go wrong with a burr grinder, I was mistaken. This grinder dances around the counter, the suction feet are of no use. It's insanely noisy. I have to hold it together when I do grind with it because the cup tries to fall off due to all of the shaking. Worst of all, the grind is inconsistent. I get fine grind mixed with chunks. I've owned this for about 2 years and it hasn't gotten a ton of usage at all. I'm replacing it with a Cuisinart Grind and Brew, at least I know that machine is reliable.
