So of the processing and the device is really top, accordingly difficult, but super quality, the blade has a very high quality. The vibration was not written here several times as annoying or extreme and that's true, it's very extreme, but it works. Although I admit, however, only 2 stars because the specified 0.1 mm cutting length simply can not be reached, I've tried the razor without attachment, no cutting length snapped quasi in the initial state .. the result is short, but 0.1mm definitely looks different, 0.1mm likely eig. only a dark "shadow" on the Bald be I am very disappointed because that was the decisive reason to buy me ...
