Defiantly generates heat
These generate heat and make my lower back feel better. Stick well and not hard to remove.<br /><br />Strange thing is they sometimes take a day before the heat starts to work. Seems to work quicker if you put the pad on and kind of massage over it with your thumbs to activate the pad. I kept one on for three days and the heat was off and on at different times.<br /><br />Don't know yet if there are any added health benefits. Would say try a pack and see if they work for you.
