Query: It's a BUY!

I have to say this is the best product of its kind. I know, since I've had quite a few negative experiences with its competitors: a lot of nicks and pinches...I'm using it for the underarm hair as well, and it hurt quite a bit when I first started. But now it's the best time-saving device for my grooming routine. My husband is amazed how little time I now spend in the bathroom!
