Fusion heat packs are made enclosing a supercooled hydrated salt solution together with a stainless steel trigger in a sealed flexible reinforced plastic bag. Activating the trigger causes a single molecule of liquid to change to a solid. This causes a chain reaction for all the liquid molecules to crystalize. This crystallization or extreme chemical faze change produces heat up to 130 degrees. The pack can stay hot for up to 2 hours depending on he size and insulation. Fusion heat packs are reusablefor hundreds of uses and are always guaranteed to activate in its liquid state. Fusion heat packs are safe and 100% non-toxic.

  • These are legit they just don't work as well as the beads.

    Also you can only click once and then have to use a bowl of boiling water to reheat.

    They don't stay heated up for long, but I prefer these over the beads because they feel better.

  • @Flitterfuzz maybe ya did it rong

  • this is a con dont' buy it, it goes solid as a rock and when you boil it it doesn't work, and they are deleteing all the comments i put in their websites because they know i am right.

  • This is a con, i just took mine back today! sigh

  • @Mclovin1161 Need to boil it a little longer. If just one of those solid crystals survive, it will re-activate. Its also why they go "bad" some times the crystals never reset.

  • My heat pack heated up fine but every time i reset it, it hardens up again after about an hour or so. Is there any OTHER way a heat pack can be triggered other than pressing the button that i can avoid? Or is it just faulty?

    Cheers :)

  • turn the lights on higher I want to see the color... is this a click heat? If so, I LOVE THEM!

  • take it back- get money back

  • @joshuanesbit I did but it didn't help

  • you have to click a few times
