The few things one hears about them:
- The dryers are not yet pefect. Tangeling, creasing and such are common complaints.
- The washers are REALLY versatile, wash and rinse just as good as any Miele.
- The QuickPowerWash cycle however is not quite something lots of people use. Only 1 rinse, and if you select Cottons at 50°C or lower, select short, and activate the Intensive option in the ProgramManager, you get 2 rinses and simmilar rythms in just about the same time.
- There are some noise complaints. Often either the transportationrods are not secure enough at the back of the machine, or the TwinDos cover isn't latching perfectly. But even then, they are flimsier at balancing yet not considerably more silent the previous generations.
Overall, not bad designs, but not quite Miele-pefect yet. They however redid them already with PowerWash 2.0 and some other fixes as well as some slight cycle changes. These models end with a 1, so 121 would be the PW 2.0 version.
