I purchased this item approximately 5+ years ago to use as a spice grinder.  We also have one to grind coffee.  There are some spice blends that I prefer to make myself, and this KitchenAid grinder does a very speedy job!! 
This KitchenAid grinder is fantastic and one that I recommend highly.!  Easy to use & clean. (This review was collected as part of a promotion.)
