This is the cutest thing! When I first saw it, my first thought was, "My god, that will make the best hand warmer in the winter!" Naturally, I ordered it. I couldn't help myself! Underestimating how big it was, I ended up ordering two of them - you know, one for each hand!

The moment it arrived, I couldn't stop myself from trying one out. It sounded simple - just snap the metal disk and watch the magic happen. Boy, it was a bit of a struggle to snap that thing! I was so afraid to rip the PVC material. Finally, I got it to snap - and nothing happened! I thought maybe it already somehow snapped during shipping, but I figured I'd try one more time. The crystals started to form and it was like a tidal wave! Within seconds, the little heart that was once filled with pink goo became a rock-solid, white, crystal-filled warmer. It didn't take long for the heat to start kicking into high gear, but it was nothing that felt harmful in any way. It actually heats up to 129 degrees Fahrenheit, but you should make sure it feels comfortable enough for you before using it. The heat lasted for about 2 hours from the point of snapping the disk to when it was completely cool, give or take a few minutes or so. It felt quite soothing! This is when I started realising all the things that this thing could be used for!

If heated massages aren't exactly your cup of tea, they can be used, as mentioned before, as a hand warmer in the winter. I don't know about you, but any time my hands are cold, the rest of me becomes cold. (Which is odd... For most people, it's their head or their chest... I apologize, I digress.) This can, and will, solve that very problem! But the uses don't stop there - you can use it for heated compresses for sore muscles or everyday aches and pains, or even for cramps during that worst week of every month. I'm sure the uses don't end there - just use your imagination!

Can this be re-used? Yes, it can! It may not be as convenient as snapping a disk a few times, but the fact that it can be reused is more than most products these days can say. How do you do it? Simple - line the bottom of a small pot with a hand towel or face cloth, to ensure that the heat from the metal bottom of the pot won't melt the PVC. Place the heart on top of the towel, away from the sides of the pot, and fill the pot with enough water to cover the heart. Let the water boil slowly until all the white crystals turn back into liquid. Note - the liquid inside may not turn back into the clear pink goo you started with. Once it is fully liquid, pull it out with a pair of non-piercing tongs and let cool for a few minutes. Again, be sure to check that it isn't too hot to use to prevent burning. Be sure not to let the water completely evaporate from boiling, and be sure to keep a close eye on it when it is in the water. If the PVC breaks, discard it and get a new one - best not to risk getting the liquid on you, because who knows what it can do to your skin! The heat from re-using it lasts about an hour and 45 minutes, give or take.
