Because it is heavy, it's a type that the handle turns to the vertical, so no extra power is required, and the comfort of grinding is outstanding. Ineffective women can also handle them comfortably. Adjustment of roughness can be adjusted freely by feeling at that time and way of brewing because it only turns the knob. We support from coarse ground to fine grinding. (No fine grinding for espresso is possible.) It is a very popular coffee mill as a gift, as well as for myself for both black and red.
