They heat very well. I tested them today in my gloves during my son's training. They do warm up, but in my opinion, the operating time is shorter than the declared 8 hours – more like around 6 hours. All the same, it's a useful gadget in emergencies. I think that if you put them in a sleeping bag under your feet, they’ll work even better. I recommend them.

Great product, they keep warm for 12 hours. Tested during a mountain trip. They could be a bit smaller and cheaper. Nevertheless, I recommend the purchase.

I'm into landscape photography and often stand in the open during cold, misty mornings and evenings, so I had a problem with cold hands even with gloves. I finally discovered effective chemical warmers, which are indispensable for me. I recommend – great stuff! Well done Militaria.

Sometimes it can literally save your life. It heats hands, sleeping bags, etc. It just happens that some batches are a bit weaker – they take longer to heat or give off less heat, but that's about 10-15% of the time.

A very good option for those with cold hands. The warmer stays warm for a long time, you can easily put it in gloves and work comfortably.

This is another large set for kids for the winter. They worked well for skiing, snowboarding, and winter scouts' events. The price is better than similar products from Decathlon.

These 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 one-fingered 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're too dry or squashed, they don't heat well.

I was surprised by their small size and attractive price. They work very well – tested even during Swedish winter ;)

These warmers are excellent, especially for people who get cold quickly. They give off a lot of warmth and last a long time, though occasionally you get a batch of worse quality. I still give 5 stars, because it's a rarity.

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

The product matches the description, maintains its temperature as declared by the manufacturer. I haven't tested it outdoors yet. Shame there aren't bigger packs available.

This is really a great product. I always keep them in my backpack, in the car storage compartments, my emergency kit and at work, because sometimes I have to spend 12 hours outdoors and, with strong winds, my hands get cold even in insulated gloves. I haven't counted how long they stay warm, but for me they're sufficient. After warming up my hands, even as the heater's temperature drops, the cold isn't as noticeable as before using the warmer. I recommend these warmers and the whole idea because they're very practical.

These warmers are nothing special. After an hour the temperature is 50 degrees, after two it drops to 40 and keeps going down. It's better to spend your money on a pair of gel warmers – those heat up to 60 degrees and are more noticeable compared to these iron powder and oxygen-based ones. Outdoors in the cold, these perform much worse, the heat disappears quickly – it's best to keep them under your clothes, not in bare hands.

A must-have for every soldier or anyone hiking in the mountains. A very practical device that helps in difficult, cold conditions. The order and delivery went smoothly, I recommend Militaria.pl as it's a reliable company.
