Super painful at least the first time through, but It sure works. My leg was red at first but it was gone by the next morning, and my leg was super smooth. (I had to do it one leg at a time, owie!) I can’t speak to how long it will last or if the hair grows back less yet. So far it’s exactly what I was expecting! I’m glad the cord is removable so you can work the angles with ease. I imagine that you could combat the pain with topical cream, oral painkillers, or booze!
