First off, I'm only using this grinder for drip coffee and it works great...when it works.
I've been getting on-and-off problems with the timer not working as expected ever since we purchased this 6 months ago. Occasionally, the grinder would stop before it reached the time it was set to. Playing with the coarseness of the grind seems to help a little, but it still stops prematurely from time to time.
Trying different beans and ensuring the grinder did not have any loose grind inside it does not seem to affect this problem.
For the moment, I've been living with the coarseness setting at maximum and setting the grind duration to the minimum setting.
I'm not quite sure who to talk to about getting it serviced, so I figured I might as well write a review.
