I've had other waist trimmers but they honestly don't compare to this one; I liked my old one, there was nothing wrong with it but this one is a million times better!
It is thicker, it is wider and the double velcro closing makes it stay put no matter what you're doing.
It is textured inside and the material is amazing, the sweat can be easily wiped off and I've even washed it in the washer weekly since I started using it.
It doesn't stay wet for long and it doesn't get stinky.
It does help warm your stomach up and make you sweat and since it is wider than the average it covers more belly for better and faster results.
I highly recommend it!
