The choice fell on the MUM48A1 because it visually fits better into the kitchen. Because I thought, in spirit to it should not matter so, what I take the machine.
It is positive that actually fit my entire accessories the predecessor to the new machine.
Negative I feel that the new machine is very loud - really much louder than my old.
And the cables "winding" is quite a hassle. At the previous model I had an automatic cable rewind, which was very convenient, of course. The new machine has a kind of recess in which you "squeeze in" the cable can. This works very poorly. In retrospect, I would have been better off with one of the machines that have an outer winding.
Disturbing I also think that the beater does not return to its original position when you switch off. Although there is a function P, by the beater to drive into the "parking position", but unfortunately it works somehow not right. When my predecessor unit of beaters drove automatically always to the "Park" position.
In addition, the machine starts so at higher load per se to "winds" that I have been afraid that part falls apart. My old machine was (although only 500 watts!) Because much more robust and has drawn strong.
Overall, it's still not a bad machine - unless you're want to edit very heavy doughs and do not mind the noise.
