This really didn't really work for me. They demo it on flat surfaces (like your arm), but it's useless across bony areas (like your knees and shins). No help at all!
The name says it all.
I bought this the week it launched and returned it 3 weeks later. Like the smell of burnt hair? then this is the product for you! Complete crap. After I perfected the speed this device needs to travel, I still had to buff, shave or wax. UGG. total waste of time and money. Buy a Tria.
