I own one of these. I can't understand what the fuss is - it's basically a lipstick shaped shaver. It is discreet and useful for use in an emergency, but in common with most shavers, you get a smooth skin - initially - followed by stubble within a day or two!
I have fair hair and fairish skin, so I don't think I'd regard my hair growth as a challenge.
As I say, it's quite discreet, so it may suit some people in certain situations.
Not entirely sure I can recommend it, but as the choice is yes/no, I'll say no, as it's spent most of the time forgotten in a drawer. The choice is yours though.
Bottom Line: No, I would not recommend this to a friend
