Received this product today, 01/19/10, and put it to the test. Broke open just one hand warmer and at first I thought it isn't working but after 10 minutes the heat just comes on and has stayed on longer than 10 hours. Measured heat at 9 hours and still was toasty 103Âº. Carried it in my shirt pocket at work and although it was not needed for my job, it certainly kept me warm in the pocket area for the time I specified. Handy little packs that I intend to take to the semi-annual gun show at West Point Ky in April as it is cold up there!! I give this 5 stars all the way around as I was quite impressed with the heat it gave off constantly for that long of a time period. Just the right size for gloves and stuffing one in each boot sock (will try that in April). Thin and lightweight with no moving parts and you just expose it to air to get it going.Great product and I would recommend to anyone who likes to keep toasty while outdoors. I know there are a ton of products on the market that keep you warm but these are Boss! They are about the size of a credit card in length/width and maybe Â¼" in thickness. Can't beat that!! Just mad at myself for not getting them sooner during my twice yearly forays to the gun show in Ky. Mike in sunny Fl.
This product proved to be an excellent deal. Usually i buy these individually at Modells or Sports Authority, for Snowboarding.. This save me a trip to the store. And great for the Mountain!Def. good choice
Good product, fast delivery. Very helpful in keeping hands warm when inserted into gloves. Would suggest company also make little ones that would fit into the fingers of gloves 'cause the handwarmers don't quite get to fingers in extreme cold.
