I bought the warmers for my husband, who is starting his adventure with the army... During the recent -15°C frosts, they worked great; my husband puts them under his gloves and his hands stay warm all the time. Even when he came home after 10 hours, the warmers were still hot. The more you squeeze these warmers, the more heat they give off.

I use these warmers not only in gloves or pockets during severe cold, but I have also found an unconventional use for them in airsoft, especially when the temperature drops below zero. When using a replica on green gas, I have to account for the drop in gas pressure in the magazine when it gets cold, which negatively affects the performance of the replica and sometimes leads to more serious problems – after a dozen or so shots, the gas can cool down too much, and the valve will remain open because the slide doesn't return completely to the rear. Thanks to these unassuming pouches, which I stick to the sides of my magazines and place at the bottom of the pouch, I can play normally even at -10°C, while without them, below -5°C there is already a risk that the replica will stop working. P.S. The warmers activate when exposed to oxygen, so to make them heat up faster after opening the package, it's worth shaking them vigorously.

Unfortunately, the heaters are very weak, they warm up to about 30 degrees at most, and after an hour's walk they weren't warm at all. I don't recommend them; they're not worth buying.

They heat very well. Today I tested them in gloves during my son's training. They provide warmth, but in my opinion, the operating time is shorter than the declared 8 hours—it's more like around 6 hours. Despite that, it's a useful gadget in emergency situations. I think if you toss them into a sleeping bag at your feet, they'll work even better. I recommend them.

Great product, keeps warmth for 12 hours. Tested during a mountain expedition. They could be a bit smaller and cheaper. Despite that, I recommend the purchase.

I definitely do not recommend buying this. It is the worst product I have bought on Militaria. The warmers do not work at all – their temperature is a maximum of 15-20 degrees, so they are useless. I checked half of the package and all of them were faulty.

I do landscape photography and I often stand outside during cold, foggy mornings and evenings, which caused me to have problems with cold hands even with gloves. Finally, I discovered effective chemical warmers, which are indispensable for me. I recommend them—great thing! Well done, Militaria.

Sometimes it can literally save your life. Heats hands, sleeping bags, etc. Sometimes, some batches are weaker—they take longer to heat up or don’t get as warm, but that’s about 10-15% of cases.

Very good option for people whose hands get cold. The warmer holds heat for a long time, and you can easily put it in gloves and work comfortably.

This is another big set for the kids for winter. They worked on skiing, snowboarding, and winter scout camps. The price is better than similar products from Decathlon.

They clearly improve comfort when working in severe frost, especially when you can’t move freely. They heat with varying intensity, but that’s forgivable. I recommend them.

A practical gadget for winter trips. They work best in single-finger winter gloves, but you can also use them for your feet or in a chest pocket. You just need to make sure they are properly aerated—if they are too dry or squeezed, they don’t heat well.

I was surprised by the small size and attractive price. They work great—even tested during a Swedish winter ;)

These warmers are excellent, especially for people who get cold quickly. They give off a lot of heat and keep you warm for a long time, although sometimes there are batches with poorer quality. I still give them 5 stars, as that’s rare.

This is the kind of product that can save your life ;) I always try to keep a supply in my pocket in winter, especially when I spend time outside and can't light a fire. The downside is sometimes you get a batch that heats less or takes longer to start working.
