Anyone have some first hand advice on some of the different battery hand warmers? met a couple yesterday that had some, probably the size of a credit card, 1/4" thick she had them in her pockets to keep her core warmer. I can't find the ones they had. looks like 1,000 options on amazon and other places, recharge with a usb, just looking for some first hand "these worked good or didn't last"
