I've been wondering about these. Thinking about getting one to replace the need to shave every week and hopefully reduce the hair to almost nothing after a while. My main questions are whether they're safe on sensitive areas like the scrotum and butthole areas and the nipples and whether or not I should get a mid-range $250-ish USD model or save up and get one of the higher end $400+ models or of there's even enough of a difference to matter. Also I'm sure it hurts but how much does it hurt compared to, say, waxing?
