I have the device now a year and would like to revise my ursprpünglich negative review:
I must say that I am quite happy after a year now:
The dishes are always clean, no matter how dirty it was before and how long the leftovers were previously dried (the machine is running at me that only once or twice a week).
The VarioSpeed function brings but if at all only a slight advantage because the device almost always also if it's not full or the dishes relatively clean actual 140-148 takes minutes, which is quite long in my opinion.
The drying function is satisfactory: Although I now always use sufficient rinse aid, the dishes are sometimes still wet, but what `s, overall I'm quite happy now!
