Sometimes razor, sometimes mower, this is a truly multi-purpose device. The effect "three days of beard" is immaculate and haircutting is no problem to length. Even the hairs of the nose and ears can not resist. The grip is very good .. The heads are easily changed in a jiffy and are all effective. Nothing regrettable side autonomy. All equipment fits in a travel kit. Without cutting the hairs, I would say that overall it is a good device but which is more suitable for fine hair as thick hair. What is an embarrassing hair.
