I don't grind coffee beans. I grind nuts, seeds, cocao nibs, spices and grains. In many cases it out performs my black and decker food processor. I have been using it daily for a variety of foods. I especially like using it to grind oats to replace white flour and chopping nuts. It does everything I need safely and I feel like I'm in control of the texture I desire. It's so easy to clean. I can't imagine my kitchen without it.
