content: I am the happy owner of a Kitchenaid stand mixer and food processor (they work perfectly). I bought this item based on my usual terrific experience with Kitchenaid - WRONG. Though its clean-up is a breeze (its dishwasher safe), its use is frustrating because all the coffee grounds leak out of the grinder. Clearly the great engineering design that went into their other products was not used here. However, I have discovered that a small amount of plastic cling-wrap placed on the grinder BEFORE the clear plastic cover goes on works wonders and prevents any spills from forming. Also, I do not overfill the grinder past the max. fill line in the cup, which, based on my Kitchenaid experience and its reputation, means it should not overflow.
