Conclusion: Compared to my old razor of Braun is superior in almost every respect: he is very good in the hand, feels great with its high-quality, hand-flattering plastic / rubber handle on, looks great, is nice and quiet and is very easy to use. The only drawback: He shaved not thorough. I shaved myself extensively with the device and then immediately nachrasiert me with my old Panasonic (of course not without first the old razor completely cleaned). Result: I again can shave off a whole load stubble with approximately 0.5mm length. Apparently uses the Panasonic significantly lower than the brown.
Have the unit returned (without any problems as always with Amazon) and now wait until I find a device that great other properties with the blend of what I first expected: a close shave.
