My wife has dragged this mixer about a year ago. Apart from that the part is very large and unwieldy accordingly, hung from time to time, the axis with the knife out. This part has always been difficult to clean since moved part of pureed liquid into the shaft. This Dripped then slowly after cleaning out. Today I then get an electric shock on the knob when controlling the speed! My simple gauge has measured 30 volts, felt it was more. The GFCI could not turn off - the device has no protective contact. To my knowledge, this device may thus not be sold in Europe. That WMF for as a China-scrap is hergibt his name, unfortunately, probably a sign of our times.
