My husband and I decided to put a spice grinder on our wedding registry, and picked KitchenAid due to its reputation for quality. What a mistake! The lids for the two spice grinding bowls don't fit, so they pop off during grinding and the spice gets everywhere. The Coffee bowl, too, doesn't snugly seal to the grinding lid, so coffee grounds end up all over the place. The parts that are stainless steel work as intended, but given that no one seems to do QC on the plastic parts, I have to anti-recommend this product.
