I bought because of the tests in the Stiftung Warentest me the device. I'm totally excited and happy with it. This is my first dryer and I do not even know how I could live without him :-) The operation is simple, touch panel and the playful flashing and the melodies are gorgeous. I am always happy when I can turn it on and he tells me with his great tones that he's done. Then I'll get the perfect dry and warm laundry out, clean the air filter, pour the condensed water away and there you go again. Great device :-)
