I've been using Nood for about 1 month. I use it 2-3x week on my "down there" area. I shave everything daily, but now I'm using Nood too. I think its working so far, bc the hair is returning but less dark/coarse and less quickly then it normally does. I plan to keep using it constantly and I'm hoping it continues to reduce and eventually eliminate the hair growth and I'll get to stop having to shave daily. But so far, I am seeing some good results. I use it on level 5 for about 10 minutes each session. No skin irritation and it doesn't hurt. I'm Portuguese, German, and Irish, so I have thick, dark, coarse hair that re-grows quick after shaving. Wish me luck!
