I purchased Nood on a whim because it was one of the more affordable IPL devices available online. The first treatment was a little tricky because I was still figuring out how to hold the device and move it efficiently and effectively. By the second treatment, I felt like a pro. I completed four weeks of treatments and have already noticed a difference. I can't wait to see the results after eight weeks! I've tried every hair removal option on the market: Laser hair removal? Too expensive. Waxing? Hated letting the hair grow out. Shaving? Constant razor burn. Depilatories? Smelly. Nood? Cheap, no growing your hair out, no skin irritation, and no smell. I can do three passes of my underarms and both legs in about 30 minutes while catching up on TV shows. Win, win!
