I have owned many waist trimmer belts; however, I have never had these kind of results. Let me just say, I love sweating now (which I used to hate). The more I sweat, the better the results and they tend to be faster. My waist trimmer belt fits comfortably and does not cause any irritation to my sensitive skin. I was afraid that it would cause itching and discomfort, but it has not caused any negative reactions. If you are looking to lose weight this year, I highly recommend this trimmer belt. It will be the best $20 that you ever spend.
