After a long search, I finally decided on this but quite expensive device. After the first few weeks and several haircuts but I am sure it is worth every penny. It feels great in the hand and cuts without tangles absolutely clean. The three comb attachments for six cutting lengths that lie neatly in the top stand are simply aufzuklippen on the device. The cleaning of the removable with light thumb pressure Scheer head is easy, especially since the cutter blade can be folded. The NiMH batteries are interchangeable, the charge cycle takes either the top stand or directly on the cable under one hour. Cable operation possible. Automatic voltage adjustment 110-240 V. I am totally satisfied with this really high quality device. Highest rating level, professional hair clipper, buy recommendation.
