I've been using Nood for 7 weeks now. My legs are super smooth and I'm looking forward to completing the treatment in a week or so to see if they really stay that way. It seems like I may need a couple extra treatments for my armpits and bikini line to really be hair-free, but the hair is definitely growing in more slowly. Because I'm doing so many areas, it takes over an hour for each Nood session (twice a week). You have to go over every area 3 times, so it takes a while and the device is loud, but I can watch TV with subtitles while I do it. Doesn't hurt at all. Overall, I would recommend this. I'm excited to never have to shave or think about shaving/waxing again.
