This trimmer is a total letdown. Even during the first use turned out that the attachment of ear hair and eyebrows, although halfway worked, the attachment for nose hair, however, totally unfit for its purpose. He smells during insertion into the nose a little uncomfortable (as overheated), but cuts no hair. But the real disappointment came only a few weeks later: Although I kept strictly to the cleaning instructions and the trimmer cleaned after each use (about once a week), the ear hair attachment was after only a few weeks to gradually the spirit. Because the thing is designed so that one does not manage to come when cleaning the locations and parts on which to fix the most dirt, and thus the blade is always difficult to move after just a few uses. At first I thought the batteries were exhausted, but also the insertion of new batteries did not help. Also, a disassembly of Scheer head (in this you can remove a portion of the housing easily and reassembly) and oils of mechanics with a suitable low friction oil (The same advantage I have long been successful for my hair clipper) did not improve. After almost half a year the unit presented then finally the service a. The ear-hair trimmer is now so stiff that the engine of the trimmer is no longer able to move it. This device is a waste of money out.
