When I used the shaver for the first time, I was amazed by the thoroughness and speed of the finished shaving, but the second or third time, probably left behind the blade of the middle trimmer, whose sides are in my opinion too freely, not clearly visible cut marks that looked like flat scars that then but after a few weeks already completely disappeared.
So for me too uncertain. If the risk is not received, since the sides of the central trimmer are much too freely.
