I have been using epilators for over 10 years now with amazing results. I have the emjoi gently and at first it was painful but over time you develope a technique which includeds making sure the skin is taut, hair is short, and working in small areas. I now have hardly any hairs on my legs. They became weaker as time went on and I use the emjoi under my arms and bikini line which has also become easier with time.Try using on the front boney area of the leg first and with a bit of mind over matter you can do it.
I now use it and feel nothing and probably only have a dozen persistant hairs left on my legs which are so weak I can pluck them with my fingers.
I think they are brilliant
