Me, not only a half times pepper Tomaste, but "large area" eg seasons a casserole or a larger amount Buletten- / Frikadellenrohmasse, doing the part - in the truest sense of the word - hurt. In the thumb, operates the pushbutton.
The knob is - seen ergonomically - in the wrong place (a lot better if he were mounted on the side, as with other electrical), and the pressure point is much too hard!
In my comparison of electrical WMF and the "old ways" of the Rösle Rösle fares better by far. The Rösle to get much faster and easier to its result, the filling is simple, also need not be six AAA batteries or rechargeable batteries!
And the thumb also does not hurt ...
