Hot to Go Reusable Heat Packs - Buy 4 Get 4 Free!

Mesmerized after you snap the metal in the pouch to activate the heat. Gives off good heat, not burning hot but tolerable. Made well! Read instructions and boil for 10 mins. after use to get back to gel. Pain relief is an 8 out of 10, very easy to use, design is perfect for minimal notice and small areas, very effective and extremely flexible. Great product!!

Very good hand warmers and great for the price. I really like these because they are very portable and you can take them anywhere. They have no smell and create a good amount of heat. One thing I wish it had was greater life span and had heat for longer. Another thing to note is that i think they can get a little bit less effective the more they are reused. It is also kind of a burden to have to boil them every time you want to reuse them. But overall i think this is a great product and diffidently one that you would want in the winter.

I bought these as stocking stuffers for my wife and kids and I'll say upfront that I'm pretty happy with them. Positives...All 4 packs seem to work as expected and none of them had already "activated" in shipping. They heat up quickly and at their hottest, feel warmer than those cheap throw away ones...I say feel because I haven't actually tested the temperature. Boiling to "recharge" them was no big deal and I like that they can be used repeatedly as I try to avoid creating needless garbage when I can and the throw away ones are needless garbage. They are made of a thick plastic/vinyl material and while I'm sure I could rip one open...they don't feel cheap. On the downside...Like some other reviews have mentioned, the initial activation took a few tries to get it going and I was worried that they were duds. But we just kept trying and they eventually started. On subsequent uses they seem to trigger right away. So I'm sure it just has something to do with breaking in the activator. If you have trouble getting them to start, just keep clicking the little metal disc and it'll eventually go (probably). Also, I wouldn't say they really last as long as advertised. 30 minutes on the larger size is about the max and probably 20 minutes on the smaller size. When started, they quickly hit their peak heat output and then slowly start to taper off. I'm wondering if they might last longer if they were wrapped in something? Not sure on that but I'll probably see if I can figure something out. But yeah, overall they are nice and I'm happy with the purchase.

These things are awesome! I bought them for my husband who is recovering from myriad serious illnesses. As a result of being so very sick, he lost 35 pounds (he was only 150 lbs to begin with) and has been struggling with a lack of warmth in his extremities. I placed a pair under his hands while he was shivering under a blanket - immediately he was his hands began to warm. He couldn’t stop commenting on how comforting they way - it almost brought tears to my eyes to see the volumes of relief he experienced. The heat packs stayed nice & toasty for about 30-40 minutes, which was just what he needed. They’re super easy to prepare for use again; 10 minutes of boiling, remove & let cool. My husband said it’s the best gift I’ve ever given him! And speaking of gifts, the way these are packaged is perfect for gift giving. Each set of two are packaged separately in their own sealed box. The boxes are very attractive and would be perfect to give one to 4 different people. If you have a friend that is recovering from any type of illness, surgery, etc., I honestly think a box would be a tremendous gift. I can also see that they would be great for anyone dealing with anxiety or upset because they are so soothing. I highly recommend these heat packs; there are so many different ones available on Amazon and I am very fortunate that I selected this brand. Lovely gift idea for someone you care about… and treat yourself to a box as well! If I could give these 10 stars, I surely would.

Quick Activation and Long-lasting Heat: I've had these warm compress gel pouches for a while, and they're fantastic. Activate them by bending a metal piece inside the bag and you get instant heat that lasts for a solid 15-20 minutes. I've used them for everything from relieving cystic bumps to soothing muscle and period cramps. Resetting is a Breeze: Resetting these pouches is pretty straightforward. Boil a large pot of water, gently lay the used bags in it, and let them simmer for 10 minutes. No need to stir or move them around. Once they're done, lay them flat on a kitchen towel to dry. I usually do this over my morning coffee—it feels effortless. Travel Tips: These pouches are great for travel but remember, you'll need boiling water to reset them. Simply pouring hot water over them in a metal ice bucket won't cut it—they'll harden up again quickly. And don't even think about microwaving them! If you're in a hotel, maybe room service could help reset them for a tip. Overall, these pouches offer great value. I'll definitely be bringing them on my next holiday. Highly recommended!

I have been on the lookout for the best type of hand warmers for three different situations: (1) for emergency preparedness, (2) for kids' hands while biking year-round on the cargo bike (they get quite cold because they're stationary behind me as we ride through the wind), and (3) for the school aged kids as they walk to school and at recess. I considered disposable hand warmers (but don't like the waste), electronic hand warmers (looked too expensive to start with), and these. I was especially drawn to the low price point + the fact that these are reusable. As we've used them the last six months, however, my biggest complaint is that their heat simply doesn't last long. They only have 10-15 minutes of good heat and then they become bulky rocks in the kids' pockets. This makes these nearly worthless for emergency situations. I started keeping them in my pannier for cold hands while biking, but I have now found 3 that got punctured and then crystalized all over the inside of my bag (ugh). I also keep finding them hard in the bottom of the bag, having gotten activated from the bumping while we were riding. Together, that makes them less than ideal for bicycling purposes. That leaves me sending these with the kids on their way to school. Because it is a short walk, this has been by far their best application. The kids take two apiece: one to enjoy on the way to school, and one to crack open at recess time. They're very pleased with this, and share with gloveless friends on cold days. Even the school application has its issues, however. The biggest problem is that these are fairly cumbersome to "recharge". It takes about 10 minutes of boiling to get them reset, which we do when the kids come home from school, but then I have a sopping wet rag every single day (because of the boiling instructions I found on YouTube) that needs to be dealt with. That means it's roughly the same amount of boiling time as actual use time, which feels slightly absurd. In order to not waste water, I let the water cool and then use it on my house plants-- but that's a lot of water when we're using them every day! In an emergency scenario, finding that much water to boil and having a fire to boil it sounds like a lot of requirements for a mere 10-15 minutes of hand heat. Would I give these another chance? I don't honestly know, but only for the school application if I did. I will next try buying an electronic hand warmer (and then eventually buy one per family member if the first one tests well). Even if the electronic ones work out, I may still continue using these reusable ones for school because they are so much less expensive-- and therefore I am much less worried about these getting lost, stolen, or broken in the school context. For emergency preparedness, I have thus far purchased a large stock of the disposable ones for our 72-hour kits and our car emergency kits because at least I know those work very reliably, even if they unfortunately get trashed afterwards. The electronic ones may replace those, so long as I keep them well charged during normal times, and perhaps I would keep a couple of the electronic ones on my bike. In all, the search continues. These are inexpensive and definitely work in limited scenarios, but they're also short-lived heat and a lot of work to maintain.

Been using these regularly for about nine months with no issues. They heat up quickly once activated and give about 30 to 45 minutes of heat depending on conditions. I usually use them on my lower back for pain caused by spina bifida. I have also used them on my abdomen for menstrual cramping and tenderness. They can get very hot in the beginning so I do not recommend placing directly against skin. I put them in a sleeve from the air activated packs. To reset I wait until I'm down to my last two. I used to boil them individually, but now I put them all in one big pot. Takes about 7-10 minutes to reset to liquid, but the cool down for actual use is closer to 45 minutes to an hour. Pros: 1. Reusable 2. Quick heating 3. Portable Cons: 1. Cool down time after boiling 2. Activator badge can be tricky to get right at first Tips 1. Use a bandage wrap or heat pack holder to secure in place for areas like back, abdomen, arm, leg, etc. 2. While resetting make sure pouches are completely before removing from water or else they will crystallize and need to be boiled again. 3. Massage the pouches while activating. This makes them less hard and feels like heat lasts longer.

Great reusable product for emergencies. It does only last 30+ minutes depending on massaging it after activated. 1 major flaw which is more on the user is don't give it to a drunk friend and say crack this to activate. I just wanted to show off this cool product. But the drunk genius friend thought it was like a glow stick and needed to break the internal activator so he slapped it over his knee which caused it to explode all over me, him, and my truck! I regret offering him a ride to a show for his birthday but I also didn't give him an exact explanation that he only needed to bend the internal medal tab. He went out covered in the (luckily non toxic) fluid. Heard he glowed like a 15yrs old bath towel under black light at the club. And my truck is still covered in the chemical and smells of it. But starts to clean up with a warm rag. It will eventually fully clean off. I'm down one of the larger packets and we both have a story to tell. But don't use it for any impact sport like skiing. Have them for emergency survival and they do work for that of needed. .....
