I swear on BOSCH, my tools from Bosch never disappoint me. Unfortunately, this hair is very disappointing. After just a few uses some of my hair caught in the rearward venting zone and have keyed that now it's double trouble. Unfortunately, you need a special share screwdriver (the one certainly can not buy in hardware stores and Co.) to open the hair and remove the hair can. And sending the hair to repair, not really worth it at this price (Knap 15Euro). Especially because the real problem is not resolved. Now look more closely at Föhnkauf back Haaransaug-protection devices. My conclusion: For men and women suited with short hair, but not for long-haired!
