I've had this a month, and I don't think it's a weight loss machine. I do think it works for massaging the spine, and great to use after being to the chiropractor. I also use it for 10 minutes everday during the week to warm up my muscles before doing my cardio workout. Weight loss, I don't think so. If you buy this, and you don't like it. It comes directly from the manufactuer, so their is no return peel, and stick. You have to pay to ship back, unless defective.
