I've had this grain mill for years and have used it primarily to grind wheat berries to make flour. It's excellent and easy to use. It's adjustable so you can vary the texture of your flour. You can only grind one hopper at a time, however.If you do not let the KitchenAid to "cool" before grinding another hopperful (I'd guess about 10 minutes) it can damage the motor of the mixer. I learned this the hard way!
My parents bought me my new kitchen aid for a house warming gift and I love it!!! Very easy to use and clean. And it looks great with my other appliances.
