I bought this during their Black Friday deal. I have been struggling with a small patch of stubble on my chin for a few years. I almost pick every other day. I've only had 3 scans of the area now in the last couple of weeks and the results vary wildly. There are still a few hairs left, but overall, I don't have to pluck nearly every day. I'm pretty sure if I'd been on a more consistent frequent schedule they would have gone away completely. You can definitely feel heat on the flash but not painful at all. I use it at the highest setting on my medium olive skin. I have course dark hair. I started using it on my bikini line this past week now that I've confirmed I don't have a negative reaction.
