My experience with the device: It looks valent, the feel is good due to the rubberized bottom, the engine running quietly. Also the length adjustment on the bezel appear thoughtful. After this positive first impression, I was glad to finally keep a good beard trimmer in hands. But gray is all theory. In practical use, the device has very great weaknesses. The tines of the comb are distance toward the end open, not rounded, and very, very sharp. If one stays in a fold of skin hanging it or resets the device eg on the upper lip wrong, the poking quite well. I can also confirm that change the length of cut unintentionally when the unit will not recognize them exactly flat. Perhaps all this is with adequate exercise better but for me is not so what.
