Second time I am reviewing this grinder - first time around it was great, until it wasn't. The thing sounded like a 747 on full throttle. Kitchen Aid was gracious enough to replace my unit and the second one has been fine for about ten months. Now, the amount of static the unit produces makes it almost unusable. Every time I grind, coffee grinds flies all over the place. Dumping it in my coffee maker basket - same thing. Grinds all over my counter top and cabinetry. And yes, I have maintained and cared the grinder - cleaning periodically as suggested. They should make this very expensive unit with a glass canister, not a plastic one.
