WMF stands for quality. Test, I had bought a WMF 0661579990 salt / pepper mill with Depot as Peppermill. Since she has convinced me, I have now bought later a second mill as salt mill. You can either grind to a depot as well as directly into the feed. In Vergelich to other mills it is shorter and thicker and thereby keep very well in the hand. Because it is operated with "muscle power", an empty battery can not be surprised.
