I haven’t been able to find much on the no! no! either, because all the posters I’ve read elsewhere say that they gave up due to time, smell, or ineffectiveness.
I bought it, I tried it, it didn’t remove much hair, and I still had to shave immediately after. So, honestly, I stopped using it. You can read another user’s experience (very similar) at juicefairy.com. I think her post is called “I try the no!no!”, and they sent it to her for free so that she could blog about it. But even she gave up and says she can’t report any real result.
