It needs 15 minutes boiling in the water :(
Very misleading , and very expensive. It has nothing but a chemical in side a plastic bag. You need to put it in a pot and then boil 15 minutes . Then it will be hot and then you have to put it in the belt and you have to wear the belt . your belly will be burning like hell. This is  the method of their weight loss. Wish they were truthful in their tv add , it's a complete rip off.
