Best activator type
I love these instant packs and have 4 different brands, one from a kiosk at the mall (Repeat the Heat), two from Amazon (something no name made in China) and one Heat Wave a friend passed on. The Heat Wave (and the HotShotz that seem to be very similar) products have the best activator because the metal is enclosed in a rubber 'button' and will not activate accidentally. This differentiates these two products from any other similar ones. Every other one has exposed metal button which activates very easily...<br /><br />Regarding the benefits, if you need heat, if you like heat, this is a 'anywhere thermophore'.
