This device is amazing for laser touchups. I had lasered some parts of me years ago and then I had some stray hairs and light regrowth. This device doesn't work as well on all parts of the body, however it works amazing on underarms, as well as bikini. Every few months I touch up and don't see hair for a long time. I don't think it works as well on legs, where hair tends to be thinner than underarms (at least for me). It's great to have an at-home device to use.
