Bought this grinder just after Thanksgiving in 2015. This unit has been used less than two dozen times to grind spices and coffee only. Today I went to grind coffee and the grinder does not work. The motor runs but the blade does not turn. Upon further inspection as to why the grinder is not working, I found that the cheap rubber material teeth that contact the METAL bar that fits between them to turn the blade to grind have worn off and will not maintain contact with the bar. If I could've rated this unit with zero stars I would have mImam quite disappointed that the unit, at this price point, only lasted a year and is just outside the manufacturers' warranty. Sadly Kitchenaid used to sell quality large and small appliances it appears from this experience that is no longer the case.
