That was a really nice surprise! This isn't my first laser hair removal unit, so I set it to 9 and started on my legs without reading the full manual, and....I wasted a lot of time on the wrong setting! These units only do a small rectangle of skin at a time, and you have about a 30 second time between flashes, so it's a time-consuming job each time. But the laser works!! You don't need to do it often, but when you first start, you do it every week to catch all the stages and cycles of the different hairs' growth. It will grow back lighter and lighter, and eventually not at all. The knee hair is the hardest to get rid off, and pubic hair too, but I WILL eventually get it all killed! The first/easiest hair to kill completely was my underarm hair, and once it's gone, it's gone- and good riddance! I just do a maintenance routine every couple, or few, months now, on my legs & private parts, and just the areas that still grow hair. It's just a miracle that they invented these units for home use, because at a dermatologist or salon, each treatment costs hundreds! This is pain-free, and you'll save time and a fortune on razors and wax that you'll no longer need. Men can benefit from one of these too (and I wish they would!). The only thing is, if you have dark skin, it won't work for you because it targets pigment- you have to avoid moles, too (but I really don't worry about that enough to avoid every mole). Also if you are a natural blonde or redhead, or your body hair has turned grey, you probably won't have enough pigment in your hair for the laser to read & target the hair root. My hair is naturally light brown & my skin is lighter, so I'm lucky in that way. Good thing I started this before all my hair turned grey!If you are buying this for the skincare lights, so far all I can report is that it doesn't hurt to use! It sounds like a helpful thing for scars (which I have many of, so I'll be trying that light!), fading dark spots, speeding up collagen production, etc, etc, etc.! You have to avoid tattoos, but that isn't hard because the light goes flush to your skin, and is such a small area. If it really does what it claims for skin, this is a great bargain!It comes with a good manual, a nice long (complete) power cord, light-protecting goggles, even a razor. The box is sturdy and is plain white if you don't put the slide-off information cover back on, but for the money I'd think it should have at least a semi-nice case for it like my other had. But still, it's a really nice unit, and worth the price tag, believe me. The benefits are incredible!!
