here is what i thought of it.
i bought it to do my legs... i dont recommend it. it was too large of a surface area. it took way too much time. it works, but i recommend it for smaller areas unless you have way too much time on your hands. i ended up selling mine to a friend who just uses it for some hair under her chin. she loves it, but again, the time factor. there is a slight odd smell, almost like something is burning when you first use it but its not too bad. it doesnt hurt to use and its easy to handle.
so what i am saying is that if you are going to use it, try small areas and not your legs because it is not a quick process.
