The device is easy to use and has enough laser pulses that I think most users will last a lifetime with it. The 2 year warranty is also very good. There are various settings to target specific areas/hair types. It doesn't hurt, although my skin gets a little sensitive about an hour after application. I use this on my underarms and the swivel head is perfect for that area. It works well enough to be removed; it's hard to tell if it will be more successful in the long run than professional treatment. However, it's much less expensive than a salon treatment, and more effective than any other home treatment I've tried.
