After use, you have to boil it to reset it (until hard crstyals are liquid again). Lasts a good while, lasted about an hour for us but I know it depends on how cold it is outside. Doesn't burn my skin and easy to reuse. For what you pay, I think it's worth it as a quick buy. Size of my palm. I like the panda, brings a smile to my face in this cold world.

I’ve owned many of these over the years and this is the worse ones I’ve ever purchased. Hard to activate the clickers are difficult to activate and once activated they don’t keep heat. Most last 10-15 min these barley get warm and lasts a minute tops big waste of time and money.

These things are pretty neat and I didn't even know they existed until I watched the video online. I ended up getting them to try to keep my son's food warm and his lunch box. The only problem though is all the heat makes everything soggy in his lunch box. It's a pretty neat concept though, there is like this metal thing inside of that and you click it and it makes the whole thing turns solid and warm. Then when you're done using it you put it in a pan on top of like a washcloth or something and boil it for 5 minutes and it goes back to being liquid until you're ready to use it again. Very interesting product and it does what it says I just couldn't use it for what I wanted.

So far has worked great. Will buy more to have on hand

I have gotten the same experience as many other reviewers have mentioned. They don't stay warm for very long at all. I would estimate the useful heating time to be about 15 minutes only. After that, technically they do stay warmer than room temperature for an hour or more, but the difference is so small that it doesn't really help as a hand warmer. I have also had difficulties getting the reaction to start. A couple of them would not start after flexing the metal piece. It took 10 minutes of repeated attempts and flexing from different angles, positions, speeds, etc. to finally get the last one to work.

Good product, nice price. Love them

Half of them didnt/don't work, they don't get hot enough, and they only last for 30 min.

These are so cute. They came exactly as described. They stay warm for some time. I really like these.

Product didn’t work. Most of the clickers don’t work. On the one that the clicker worked, the chemical reaction didn’t engage so no heat

Très sympa mais ne chauffe que quelques minutes

En su primer uso calientan bien, aún no los e cocido para reutilizarlos, pero si que son muy sensibles y hay que guardarlos con cuidado para que no se activen solos en la mochila

They work well with each one giving a decent amount of heat for a few hours.

Fantastisk produkt; fungerar över all förväntan. Om och om igen.
