The light on the highest setting kinda feels like a light snap to your skin with a rubber band. Not bad, but doing the 3rd pass can get kind of intense. I've only been using it for about 3 weeks, so progress isn't crazy so far, but I believe there IS progress! Picture included is of bikini area (my main concern). I had always waxed, due to this about half my follicles stopped producing hair. The Nood is to get rid of the remaining growth. The pic is a week of growth after using the Nood approx 6 times. It does look like the growth is lessening. Will be keeping track of progress!
