I haven't tried it but for that much money you should really consider and give it a second thought. It's way too expensive if you ask me. The bottom line is you still gonna have to work either way. So I tell you right now to jump rope for 50 days for 30 miniutes a day you will gain inches for sure. It's not a secret, it's practicing.

But if you really really can afford that then go for it.
