I love Whatwaist products! I have ordered a variety of bands from them and always recieved them quick (Within 3-5 days). Due to the compression, the bands can fit a little tight but not to the point where I can not breathe or feel uncomfortable. The more you wear it, the more you get use to it. It contributed to weight loss for myself (Of course I exercised and ate a healthy diet as well). The bands are made out of strong material and have held up. I do not understand all of the negative reviews. I have never had any issues with this company what so ever.
