Also I am guided by test reports and reviews here. I like that the device is very handy. Unusually, however, was that I feel through the silent motor, the performance is not there as I was used to from my previous agitator. This has really losgepowert with fewer watts and here you can hear a faint hum and must also stir longer. At first I thought the unit was broken. Well, since I mainly need to knead bread dough around, I'll see how long hold out the Bosch stirrer. The previous device has made it for 3 years.
