Has anyone tried sweet belts?

I’m not overweight or anything, but I’m starting to gain a little weight in the stomach area and have been wanting to try a sweat belt this Summer to hopefully sweat off some water weight at least. I do work out like twice a week. Has anyone tried any sweat belts? What brand? And has it worked? It’s extremely hot and humid where I am, so I know I’m going to sweat a lot.
