As a long time kitchen aid owner, this is an attachement I have longed for. It works quite well for simply cracking whole grains or milling whole grain berries into fine, whole flour. Insufficient for milling all your flour needs, it is great for small batch milling such as making your own sprouted grain flour to add to breads. I recently made a two loaf recipe of spelt bread and in the interest of pioneering challenge, I decided to try milling all the flour required for the recipe. It was a doable task with this mill, but it took 30-40 minutes to get the 1060g needed at the finest mill setting and at the end, everything was quite hot. In the future, I will only mill a hopper's worth before letting it have a cool down period. For me, this makes whole recipe batches impractical. None the less, very happy with it!
