Works very well on my neck. Gives off alot if heat.

This was a great idea if it worked. Only one pad heated up for about twenty minutes. The other three did not heat up at all. I tried and tried, but they would not work. It was easy to use, but did not work. The item was small and compact, perfect for a designated spot. Would not buy it again.

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.

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.

My mom got a shoulder heat-pack off this type and I was totally amazed! So I got some small ones to try. I wanted to get some that were easy to boil back to liquid. Anyway, this didn't crystallize on the first click but it did on the second, and it's warm! Not sure how long it will last, but if be happy with an hour or more.

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

The product works as described, but I'm disappointed the heaters only stay warm for 25 minutes at the most. I was expecting the heat to last longer. Also, I had to return the first set I ordered, as 1 heater broke after the first use.

The pouches have very little substance: 47g (1.6 oz) total weight and produce very little heat. Laughable at $3 a pop. Pouch material is extremely thin, filling welds are sloppy and carelessly made. First pouch immediately sprung a leak when re-charging in the microwave, relegating it to the trash can. So now I can not even return it to Amazon. $12 in the crapper. Live and learn.

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

Súper bien, súper contenta, me va fenomenal para los paseos cuando hace viento y frío para cualquier ocasión la verdad ya no me voy a separar de ellos, me va a ir bien para ponérmelo cuando me duele la espalda, también cuando tenga dolores de regla, también me lo voy a poner en la tripa. Me lo acerco a la cara y me la calienta un ratito. La verdad es que ha gustado.

Realmente funcionan proporcionando calor por un tiempo razonable (30 min.). Son reutilizables, solo las pones a hervir por unos 6 min. y se vuelve a su estado líquido inicial, dejarla enfriar a temperatura ambiente para reutilizarse de nuevo. Recomendables para cuando se requiere una compresa de calor y portátil.

Perfect
