The Panasonic machine is called "professional" -Haarschneidemaschine probably rightly so. Now I myself am not a professional in the area, the unit 1 x per week but sit for 2 years at least one -. Without any problems to the device or battery. Super performance, is very precise, well in the hand and is also very stable (has survived the occasional crash). Wehr more wants than the comparatively simple competitors, of which I have already tried several, including several brown-hair trimmer, has invested his money well.
