20 Snappy Heat® Reusable Gel Heat Packs—Instantly Hot Pocket-Size Heaters Provide Soothing Therapy for Cramps, Arthritis, and Pain in Joints, Back and Neck Muscles

This is not new technology, and I have been looking for them for years! Although this is a different brand and look than I remember, the process is the same. Works great! No frills, not the colorful blues greens and purples used by others that charge an insane amount. These also are not the ones that last for hours. This is a quick hand warmer or something of that nature. Maybe even a heat compress for a short time. They last for about 30 minutes, give or take depending on usage and room temperature. But with 20 of them you can replace them if needed easily, and them boil them to reset when done. BE CAREFUL! I like heat, and I used this for a wrist that was bothering me. I did not follow the directions, I mean...I know what is best for me right? I burned my hand because I placed it directly on my skin. The burn wasn't instant, I had let it sit for 30 minutes. The burn also was not severe, no itchy or blistering, but a nice red mark showing I messed up.

I had some really badly produced ones in the 20 packaged variety. Mainly the round ones, the stitching or sealing method didn’t do some of these justice and one or two of them has air bubbles? In this picture I have just boiled them for about a dozen minutes to reuse and it’s unsealed and leaking. So… I wish I could get some of these returned or replaced because I do really use them and enjoy them. I’ve only used them all once, working nights as security on extremely cold weather

Good for quick snow shovel, blowing snow and other quick outdoor projects by taking "the cold edge off". We find they last, on average, about 30 to 45min; not as long as our single use hot pockets, which last for about 8hrs. We use our induction stove top, set to 275F, for boiling / recharging. We recharge 8 at a time, to save time and handling, The package of 20 gives us the flexibility to keep some always ready to go. After boiling, we leave on a cookie sheet, laying on a towel overnight, and their ready to go in morning.

Who knew that a non-toxic chemical reaction could produce so much heat and be re-used time and again? Great for migraines and sore knees and necks. My only disappointment is that the heat barely lasts 5 minutes, even in out hot climate. Still worth it though. They can also be used while still hot after boiling. The 20-pack is great because they can be boiled all in one go. I am rather frustrated that I was asked to go to a website to register my packs for an extended warranty and a discount on further purchases, only to find a message saying promo codes all used up.

These are great for just about anything. We use them during football season for our boys teams. Helps keep them warm while standing on the side line. Also throw them in my emergency kit for snowmobiling. These heat quick and last about 20mins or more. Great product

They work to generate heat but after you use them they sometimes will expand and rip the pouch open and start leaking the white foam which will harden and stick to things. These things seem dangerous.

They do not stay warm very long-maybe 30 minutes? & have to be boiled to be “reset”. The point of buying these was to use them multiple times a day since we go in & our of our building at work constantly. Wish there was an easier way to resetso they could be uSed longer

I wanted to love these. Some of them had to be snapped several times to get a reaction. I boiled them according to instructions and they recrystallized after cooling! (I even reboiled them just in case...up to 45 minutes and they still crystalized!) I now have 16 "reusable" heaters that are worthless. Don't waste your money.

Makes the cold winter weather more bearable with a Snappy in each of my pockets!

Super pour réchauffer mes à chaque fois que je les mets à bouillir j'en ai 1 ou 2 qui explose et se vide donc à long terme pas sur de la rentabilité versus des jetable
