Teleroid Winter Sports Instant Heat Click Hand Warmers, 30 Count

You get ahat you pay for. I paid $15 for 30 of them. I have now had several that do not work. Also they do not last as long as others ive seen. I only get good heat foe about 5 to 10 minutes then kinda warm for 5 more minutes. After that its cold.

They get pretty hot but they don't stay hot for very long. You would need to use a lot of them to keep your hands warm for any period of time.

Unlike the Click It Hot brand I bought at a show, these are Not the Click It quality !! after following instructions to re activate 4 of mine leaked so far and dispensed them to the trash.

great item, really cool or should I say warm, lol

These are about what I expected for the price. They work just fine, but are on the smallish side, not just in dimension, but by the amount of 'heating get stuff' that is inside of them. I've used other, more expensive ones, that seemed to be made of a little thicker material, that also seemed to have more gel inside (which meant they produced a little more heat). They are re-usable, and have lasted through several cycles so far. We always keep some on hand, ready to activate, because our oldest child is going through growing pains, and these little hot packs seem to help. Whenever we need one, we just grab it, find the little 'coin' inside (about the size of a penny) and 'click' the coin (try to bend and then straighten it). This starts a reaction that causes the pack to go from gel (liquid) to solid, and put out heat. It does not get hot enough to burn, and if you hold it to something (knee, elbow) while it is still mostly gel, it will conform to that shape as it hardens, which seems to make it more effective than if it were just a flat hot pack. I've gotten a few packs that seemed built stronger, with more gel inside, but they also cost substantially more, so all in all these are a decent value.
