Excuse me, I must be honest. The mixer is advertised as nice and quiet. For a star. That the mixer is so quiet - but is not an art - because it at the highest level just as fast as my old mixer rotates at level 2 von 5. Have just remade spaetzle dough. 25 min. later he is finally as it should be. The pain judging by - in the wrists - I can even stir the dough next manually. Come out to the same thing. Even with simple dough for sponge cake my wife is even grumble at. Siemens sat down ... Note 6. Siemens I am very disappointed! Next time I buy a blender of delicatessen Albrecht. The then also has three-year warranty.
