Due to the bad recession of Siemens WaMa (identical Bosch) I was very confused and was on my way to the local MM. This had both machines, the Siemens and Bosch, right next to each other, said Siemens, good 40 - was more favorable. Curious and wisely I inspected drums, and yes, this drum nature was quite different from other machines. With cotton pads and sensitive finger tips I felt from both drums and it is logical that these surveys the drum one feels they're directly visible. The actual holes in it struck me as problematic, if at all, then there are at most those holes that are drilled on the side elevations. My cotton pads have also survived the drum test unscathed. One thing is noticeable: The drum structure acts, compared to other drums of other machinery somewhat restless, but this must be nothing bad. Because of the price and the certainty that the Siemens and Bosch are identical, I opted for the Siemens moreover available at the Amazon recessions in terms of identical Bosch WaMa, at least at the time of recession, where at least 82 users, the device rated, not a single negative message erstrecht not in terms of destroyed laundering. The MM-seller also believed to know that it was initially Drum problems, where Siemens has probably improved. Ever should be the same as Siemens and Bosch drum suppliers. A recent WaMa of Siemens, also winner of Stiftung Warentest in 2013, has installed the same drum, but it costs 200, - more Installed and connected the machine I immediately placed and washed some shirts in the drum, of course I was looking forward to the final result: Laundry was fine, did not notice any holes or excessive roughening of the shirts. The linen did not look different than after wash my old Bosch WaMa. So far, I've been buying so no regrets. However, this recession is a kind of snapshot, because the machine is only since yesterday with me. Should the quality of laundry after the wash cycles of Siemens deteriorate noticeably, I will add this recession.
