I wasn't sure about this when I ordered it. There were no reviews and I was worried it would be gimmicky. It isn't, it's a lot like a Thera band, except that it's a lot easier to use in motion. With a Thera band you have to have a set of exercises in mind, and movements to derriere can require tying it up and rigging it poles or furniture. You can use this product while you're doing a normal barre exercise, I would recommend something easier than your normal, and it's specifically helpful for frappé derrière. Also comes in a useful carrying pouch, that can be tossed in your dance bag.
