The nose hair trimmer BaByliss convinced me from the design and the shaving performance. He is small and handy and thoroughly removes the disturbing nose hairs. But it decreases the Scherr head to rinse the blade you come across the only shortcoming of the device. The blade remains in Scherr head stuck, a simple "calibration and rinsing" is therefore not possible. One gets the blade only from Scherr head when you open it again and again on a firm surface. But this is very cumbersome :-(
