Fir Slim (XL)

This thing is worthless, Useless, I's is rip off, don't get fooled by the advertisement.I want to give it less than a star, it doesn't work at all. That's why the product is a rip off, don't buy it, don't waste your money.I bought this product in June 2016 use it for 3 months during jogging with no results.
