Only for my legs too. I always use them after a glass or two of wine and before I go to bed so any redness and tingling subsides overnight.

You do get used to the flinch factor

I wouldn't dare use them anywhere other than my legs and I do have problems with ingrowing hairs so you need to exfoliate regularly. Mind you, I had that with waxing too which I hate more.

I'd buy a Braun or a Phillips. Most have various 'lessen the pain' gadgets but it's all about bracing yourself. Keep the skin taught at all times and make sure your legs are bone dry.

The hair grows back more finely as you don't have a blunt cut as you would have from a razor. Use every three weeks or so.

HTH!
