I've got one and it has made a huge difference to my legs (bottom half). I used to have to shave them daily if I wanted to go bare legged and even waxing would last only a week but now they are good for a couple of weeks when I shave and Lumea them again. A vast improvement.
Underarms haven't been so successful but then I'm not great at sticking to their suggested schedule. But the growth is certainly slower and they feel better for being left alone a lot more!
Shop around if you do decide to get one. I got mine on amazon and it was much less than you are saying.
