I used NoNo for years (until it died). I actually believed my hair stopped growing. About a year and a half after using it, I was having to shave at least 3 times a week. I will be buying another. It's tricky to use though, you have to get the angle just right in order to roll it, otherwise it cuts on and off. I work in a cosmetic environment and can tell you it does the same thing as a laser. By the way, one laser treatment costs way more than the price of this device.
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
