It worked. We tested it during my son's training today. At minus 5 degrees Celsius, it kept warm. They heated for 3 hours. My son plays soccer. The training was individual, so there were 2 hours of intense exercise. For us, it's great. The only downside was a torn bag when taking them off. The rating is lowered for the operation time and the tearing. Overall, the product is fine. Only a bit of a mess spilled, but the shoes stayed clean.

The heaters worked great during the difficult, winter conditions of the war in Ukraine. Their runtime may vary depending on the batch, but they always lasted at least 4 hours. They are definitely better than those produced in Ukraine.

Together with body warmers, this is a must-have item on cold days. Last winter, I had to walk in the snow in summer shoes—these inserts really provide comfort and protect against freezing.

They work great for working outside at night when it’s cold or the wind is strong. It's important not to stick them directly onto the skin.

Chemical warmers work great for winter activities or outdoor work. I recommend because they work without problems and provide warmth for a long time.

Grzejki chemical foot warmers work just as well as other warmers. Worth having on hand on cold days—they can lift your mood.

At first, they heat up intensely, so you might even feel tingling in your fingers. After a dozen minutes, the warmth stabilizes, but your fingers are still well warmed. They work for several hours, useful in pockets, gloves, socks, and even in a hat. I recommend for short winter adventures.

Compact and inexpensive warmer. Thanks to its small size, you can always have it with you—in a waist bag or a backpack. Small, but improves thermal comfort.

The warmers literally saved me from freezing during a night in the forest at -10°C. I stuck them onto my sweatshirt under my armpits, on my chest, and the inside of my thighs—they worked quickly, it was almost too hot at first, then it felt pleasant. The downside is the short duration (2-3 hours), but that's understandable in such frost. They don’t work in shoes as there’s no air access. I used a lot that night, but I still highly recommend them—better than hypothermia!

A great option for winter walks in the city and tourist trips. They heat for several hours, you feel the warmth after a moment, but they’re not too hot. The glue holds the warmers perfectly in place in the shoe, and later it’s easy to remove them.

They heat great, indispensable for trips or cold days at home. They even helped me while working at the computer when my fingers were freezing. I give four stars because the temperature can vary depending on the location—in shoes they might be less warm, and in open air you can get burned if you don’t know the product. Maybe gel warmers would be better for such situations, but I still recommend these.

The product matches the description—it keeps the temperature within the range given by the manufacturer. I haven't tested them in the field yet, just wish you could buy them in larger packs.

A must-have for every soldier or person hiking in the mountains. Very practical, they help in difficult, cold conditions. Ordering and delivery were hassle-free, I recommend Militaria.pl as a reliable company.

They heat for a long time and effectively, can recommend without hesitation. The glue holds securely, so the insert doesn't move inside the shoe. The temperature is right—they’re great for walks in the forest or cold days.
