I’ve been using on level 7 twice weekly for 12 weeks. I’ve seen good results on my legs but no change at all with my underarms or bikini area- which is confusing because the contrast of hair to skin is much more pronounced in those areas. I cant seem to find any information on exactly how long it might take to see results (8 weeks seems to be the minimum, but what is the maximum?), and when I should just give up and look for other hair removal solutions for those areas. I am happy with the results on my legs, although “complete” and “permanent” don’t feel like accurate descriptors- my leg hair is much thinner , less dense and grows much slower, but I still have to shave weekly. I would also argue with the “painless” claim. Because you need to use level 6 or higher and go over areas 3x, it can become quite painful…. But nothing compared to waxing. So, if it worked as claimed I would be fine with tolerating a little pain. Over all, I’m not sad I spent money on it, but I wouldn’t do it again if I knew what I know now.
