They're fine, but you have to give them time. When I first tried one it ripped my face to shreds, but my old man said to give it 2 weeks. I did, and it was sorted. I even do my head with mine now, as I am a baldy slaphead.
2 weeks, shocking. How often do you shave? I tend to shave every 2 or 3 days, will it cope or will it rip my face off?
what sort do you have?
