"We bought your mill something like a couple years ago and have ground all of our grain with it since (Kamut, Millet, Rye, Barley, Oats, Buckwheat, Wheat), and we go through a fair bit. The mill does perform as new and we’ve had no complaints since adding a 5/8” nut (figured that out before noticing the suggestion on your website today!) on the shaft to keep the adjustment from changing when grinding very hard grains like Kamut. My background prior to programming was working as an industrial maintenance millwright, and we chose your mill for value and quality. We are glad we did. We prefer to save up and buy the best rather than buy things that break down, do not perform well, or wear out rapidly. You make a fine product.
