Excellent warmers — they heat up quickly, last long, and are really strong, ideal for winter trips. Non-toxic, lightweight, and convenient to use, they work in any situation. A set of 10 pairs is a great option for the whole season. Too bad I didn’t get to use them, because who knows when such a winter will come again...

They don't provide much warmth and overall are not very functional. Taken for skiing. There's no option to attach them to any material. I expected a better effect.

TERRIBLE. Taken to the training ground for an emergency situation. After opening, nothing happened for 15 minutes, and then the temperature was about 40°C. Maybe it could be given to children for an evening walk on a Sunday and nowhere else. And the 'Polish' manufacturer is a scam. This company is just an importer.

I have been a consumer of these warmers for a long time, they are quite versatile, for example you can place them under your foot under a sock at night in a sleeping bag outdoors. The batches can be inconsistent, but I usually get ones that stay warm for a long time.

The only downside is that sometimes there are batches of uneven quality. However, if you don't get one with problems (which is not very common but does happen), there's nothing left to do but use them and enjoy the warmth. Comfortable, packaged in pairs, they stay warm for a long time.

It's a decent product. It works well as a one-time purchase. They serve their purpose, work as intended, and you get 20 pieces in one pack, which lasted me a long time.

I tested this product some time ago. I have compared it with other products of this type and I must admit that this one meets my expectations. It's good to put into gloves when your hands get cold. It's always worth having it in your backpack as an emergency during winter.

They are okay, but I wouldn't say they are a product that could somehow keep your hands warm at night in the forest. Rather, it's an okay product, but more for recreational use.

I bought these warmers for my husband, who is starting his service in the army. During the recent cold spell at -15°C, they worked great – my husband wears them under his gloves and his hands stay warm the whole time. Even after 10 hours, when he got home, the warmers were still warm. The harder you squeeze them, the better they heat.

I use hand warmers inside gloves or pockets in severe frost, but I also have an unconventional use for them in airsoft when the temperature drops below 0°C. As a user of a green gas replica, I face a drop in gas pressure in the magazines as the ambient temperature decreases, which reduces the replica’s performance and, in critical cases, ends up in a malfunction (after a dozen or so shots, when decompression does its job and the gas cools the valve too much, it can remain open because the slide does not complete its full backward movement). These inconspicuous pouches stuck to the sides of the magazine and placed at the bottom of the pouch really make a noticeable difference and allow me to play in the cold down to -10°C. Without them, it’s impossible to play at temperatures below -5°C without the risk of malfunction. P.S. The warmers react with oxygen and to "activate" them after opening, I recommend shaking them well.

Unfortunately, these heaters are really bad, their temperature is around 30 degrees at most. After an hour-long walk, they didn’t heat at all. I do not recommend them, do not buy.

They heat up well. I used them in gloves during my son's training today. They heat up, but the duration is questionable. I don’t believe in 8 hours, maybe 6 hours at best. But it's a useful item for emergency situations. I assume that as a foot warmer in a sleeping bag, it will work even better. I recommend it.

Very good product. They heat for up to 12 hours. Tested during a mountain trip. They could be 1/3 smaller, and therefore cheaper. A product worth buying.

I strongly do not recommend. So far, it's my worst purchase from Militaria. The "warmers" do not warm at all. They might reach 15-20 degrees, they do nothing. I checked half the pack and all of them are faulty.

I am into photography, including landscapes, so I often stand next to a tripod outdoors on foggy, chilly mornings and evenings. And I always had a problem with cold hands, even with gloves on. It was a nightmare... But I finally found an effective solution in the form of chemical warmers. They are irreplaceable. For me, they're amazing. Well done, Militaria.
