Blah
This product is crap. It's way too big and slides down your head. The cords not long enough, the chin strap doesn't tighten it.  Since it's too big, the chin strap is not even needed. It doesn't get hot at all--I left it on for an hour!  Too bad I lost the receipt so I can't take it back.  Guess I'll regift it to my sister :D
