The belt really works when engaging in a physical exercise workout and eating healthy. It actually remove excessive water from your body causing you to loose inches from your targeted area. But, to wear as a slimming garment under your clothing, I would not recommend it. Also, you have to be very careful with the zipper, where it can pull away from the insulated material. I bought two of them this time and these are the third sets that I have bought. Slim Away works for me.
