Until now I had a trimmer with round shaving head and a rotating blade and worked much better. This principle here has to be removed especially in the beginning in the area of his nose hair problems.
And if he once caught a few hairs block this the knife, since the hair is not as drawn in the usual principle into the housing interior. So you have to constantly clean (well, this is a useful brush supplied), also migrate the cut hair for days in the nose around until they finally fall out. This can then mean before that you have to Niessen to client meetings and is then alerted by the customer, because the hair hanging out of your nose / in your face. Super !!
