i want to clear things up i read a review how people think its ghost pepper or something thats a lie i sweated in this belt with the heat even tho other customers said they did not sweat at all only felt heat also i put this product to my face to see if it will transfer the heat over to my face like a customer claimed and it did not have a burn effect on my face so so far i love this will keep updates as the weeks progress to early to say if it will make me lose fat but so far it does what it says love it
