I bought one for my hubby for Christmas. After 2 weeks, a mechanism inside the machine that signals to the grinder that the lid is shut stopped working. The machine would beep, but not grind. Even when we tried to turn the grinder off, the machine would only beep. We would have to place a heavy cup or bowl on top of the whole unit to get the machine to engage so we could have coffee. Overstock has wonderful customer service and promptly sent a replacement, but this one, too, started doing the same thing after 2 months. Disappointing, indeed!
