1. The product has cracks between the rubber and the shirt!
2. The rubber is of terrible quality, it is very tight and constantly pulls the shirt upwards, resulting in the area not being covered.
3. The size I ordered was L-XL, while I wear a medium, and what I received was even smaller than a small.
4. The sweat-wicking material did not work properly, resulting in no sweating and fat burning as promised compared to similar shirts of the same price that I have tried

VERY EFFECTIVE, I RECOMMEND it, I just have it for a relatively short period of time to say about its durability over time....
