Not quite painless but it is proving effective quickly. In 3 weeks of use, every other day or so, at a level 5 or 6, I have seen much slower growth in my arm pits and my FUPA. I haven’t been brave enough to attempt anything more intimate than my inner thighs and upper pubic area but those seem to have less hair growth. If the full time is effective, I’ll deal with the little bit of pain. Cons: sometimes it hurts! The sharp rubber band pain of laser hair removal. And it seems to hurt more the warmer the unit gets. I end up doing an area and then taking a break to let it cool. Maybe 20 flashes or so and it’s too warm for my skin. Pros-seems to work and is working quickly. I don’t think it takes very long. I will do an armpit after I dry from the shower. Do my skin care, then do the other armpit. Adds maybe 5 minutes. I haven’t shaved my pits in a couple days and there’s very little growth
