Would you recommend these? Do they really remove all your leg hair permanently? I keep looking at them and if I did get one then the Black Friday Amazon sales would be a great time. The cost puts me off but I've heard the cheaper ones aren't as effective. They have a £400+ on Amazon for under £200 at the moment. My teenage daughter and I have the colouring which I know works best with these machines and I think it would be so great for her (if it really works) to have hair free legs forever. They are so expensive that I wouldn't want to be disappointed. Thanks.
