At first use already came the disillusionment after the device has actually made a good start impression. First, the shaft, which also drives the rear bar wobbles quite loose around the device. Worse, that the switch probably has a loose connection! In the first three stages of the mixer stutters to a complete stop, when you hold it vertically. I was hoping for a hidden feature (a strange though) - the manual is silent on this but from. So I'm assuming that the device is defective! The disappointed but very. A cheap device would probably work better, but we had us extra for purchasing branded goods with strong motor! Stupid! Only If the complaint is with the hope of a "happy ending" ...
