This burr grinder does not deliver the consistent grind that you should expect. Whenever I did a coarse grind, there was also a fine clumpy powder that would stick to the lid. Which would make a nice coffee slushy but not a proper cup of joe. This grinder was a gift to me, so I thought I would stick with it but after three years the internal mechanism stripped the threads on the plastic hopper making it completely unusable.My advice spend another $40 and get a better made grinder. The cuisinart was bad from beginning to end.
