I'm very satisfied with this principle, robust, shapely electric coffee grinder with conical grinder. Specifically, the conical grinder continuously to the respective grinding degree can be set exactly, as I knew of an old hand coffee grinder that I could use to last over 45 years. Furthermore, Severin KM 3873 has a Portinierungsautomatik which ensures that preset quantities of coffee for example, 2 cups, four cups .... be ground exactly where the mill then turn off automatically. The grind itself is preset at various stages, which is always obtained the desired grain size of the ground material. The mill is relatively heavy, which brings the internal processing quality expressed. Compared to other "Billligst coffee grinders", with an encircling, "high-speed cutter bar" which - similar to a blender - the beans "smashed", in which case also arises heat, which may affect the material to be ground, I can Severin - coffee grinder as recommend worthwhile investment for coffee connoisseurs explicitly.
