Mil-Tec Professional Catalytic Heater - Black

Great product for people who plan to spend longer in low temperatures. It works perfectly in a sleeping bag or under a jacket. It's small enough to fit in your hand and keeps pleasantly warm. I advise being careful not to accidentally choose ordinary heaters. Initially, the heater worked for about two hours, but after a few uses the operating time increased to six hours. To turn off the device, I separate the heater from the rest of the equipment with a knife. I highly recommend it.

I was surprised how well this heater works. It heats up very efficiently, especially placed in your chest pocket. Has long operating time, is compact and cheap to run.

Mil-Tec Professional Heater - Black is well made and easy to use – just be careful not to overfill with petrol when filling.

Works properly. Lighting instructions: remove the burner, pour in petrol, put the burner back on. Both the case and the burner must be dry before lighting. Light with a lighter until the burner glows (10-15 seconds). After about 30 minutes it heats up well. To extinguish, just cut off the air supply – I put it in a jar for a moment and it worked.

I was sceptical about the effectiveness of this type of device and still haven't formed a solid opinion, as I used the heater only for testing last winter. Generally speaking, the impressions are positive. It warms hands nicely, and when I put it in the breast pocket under my jacket, it quickly became warm – I even had to slightly undo my jacket to cool down. We don't get harsh winters here, but you never know what might happen. I also think that in an emergency this device could help you survive longer in the cold.

I couldn't find a practical use for this heater! When you hold it in your hands, it heats up, but in a pocket, sock or under a jumper it doesn't work or goes out. Lots of problems with the fuel and the catalyst. It leaks at the joint. It heated for a maximum of 4 hours without the cover. This isn't a product for expeditions or survival, maybe just for fishing, to warm your hands in the car. That's just my opinion.

I wasn't sure about the effectiveness of this type of product and still have little experience, as I only used the heater as a test last winter. Overall, the impression is positive. Hands become pleasantly warm, and after putting it in my breast pocket I even had to undo my jacket to cool down. Our winters aren't too harsh, but this item would certainly help you survive longer in tough conditions.

I was surprised how much warmth this heater gives. Several hours of heat during winter outings is really a comfortable solution. After starting, you have to wait about 30-60 minutes for the device to start working at full power.

The Mil-Tec Professional heater works great. I fill it with petrol just before use, even outdoors. The device provides several hours of stable heat. I wear it under my coat, hung around my neck on a lanyard, and my clothes do not absorb the smell of petrol.

The warmer worked great during colder days on mountain hikes. Kept in my jacket pocket, it effectively heated my hands. Previously, I used disposable warmers, but this one is better because you can use it many times. I recommend it!

Mil-Tec Professional is a good and affordable warmer, but it does require some skill to use. You cannot expect it to work straightaway in low temperatures after lighting outside. From my experience, it's best to carefully fill it with fuel at home and avoid overfilling. Then, put on the heating element, lightly preheat it with a flame and let it warm up indoors. Only after that, you can put the device in its pouch and take it with you for a walk.

I can confidently recommend this hand warmer, even though I was initially sceptical. A full tank of Zippo petrol lasted 8.5 hours. The catalytic heater has already run for nearly 30 hours. For those interested, I recommend buying spare heaters straight away. I'm also testing how it works with EliCo petrol.

If you pour a little more fuel into the heater than the instructions say, it can work for nearly the whole day. Now I keep it in my pocket, but it works best when you put it into your sleeping bag before you go to bed.

Great heater, works perfectly during night watches – I put it in my pocket and it gives off good heat, so I don't get cold. It's small, so it even fits in a glove, which really matters. The heater keeps warm for a few hours, so it's really worth having.

The heater ignites from a gas lighter after 3-5 seconds. It stays warm for about half an hour, then through the pouch it has a temperature of 45–53°C, and without the pouch 58–71°C. The smell is almost imperceptible, nothing leaks. I've used it 7 times, including once as a test – it worked for 8 to 12 hours. I recommend this product.
