Haven't used the above brands, only have experience with Sweet Sweat. Many people have misunderstandings about waist trimmers and think that wearing a waist trimmer can make them thin without exercise. This is impossible. What I still have to do is exercise. Not only does it accelerate the reduction of excess water, but the trimmer forces you to tighten your abdomen during exercise. I love it so far and plan to continue using it, especially during morning exercise to flatten my belly during the day.
