MFH Silver Gasoline Heater

1. The build quality is very poor. 2. It doesn't fit in the pocket in its case because it needs air. 3. Lighting it isn't easy. 4. It smells strongly when burning extraction petrol. 5. You need a syringe to fill it, which isn't included – so it's worth buying one separately. Overall, the product is weak and it's better to spend a bit more and find something better.

A simple way to warm your hands in winter. It works very well in almost any condition, you only need a little lighter fluid. I recommend giving it a try.

I tested the device both at home and outside – I do not recommend it. In fact, I think it could be dangerous. Without the slider at home the flame is so big that I worry the petrol tank will catch fire, but once the slider is on, the flame goes out as if it wasn’t getting enough air. It doesn’t glow like described in the instructions. Outside, without the slider, the flame goes out quickly. I find it hard to imagine how anyone could wear this under their clothes, as it would surely go out due to lack of oxygen.

For this price, it's an interesting gadget. I'll see how it performs during colder days outdoors. I've tried various fuels and it worked best on extraction petrol, just as the instructions suggest – easy to ignite and works without any problem (I don't recommend using ethanol for camping burners, as it's hard to light and can catch fire dangerously). On extraction petrol, it worked for over 10 hours. Tested at an ambient temperature of 21°C – stable heating, doesn't burn. You need to be careful not to block the air intake. In your pocket or in your hands it's best in a pouch with loose drawstrings. It could hold about 35 ml of petrol inside (measured with a syringe). Be careful not to spill or overfill the fuel and observe if the cotton absorbs it while pouring.

As a cheap warmer it's fine. There are difficulties with lighting it, later you need to ensure proper airflow because it often goes out. In room temperature it heated for a long time and steadily, but under clothing and at lower temperatures problems appeared. It's more suitable as a backup for something better.

For this price I'm satisfied, I don't expect more. If someone has higher demands, it's better to choose Zippo.

It heats up, but smells a bit.

It heats hands well.

I can't fully recommend it, if anything it's better to spend a bit more and buy a Zippo, although this one also works.

It heats gently but evenly.

The hand warmer is worth its price.

Very good quality, fulfils its function, I recommend it.

The quality matches the price, the hand warmer goes out in your pocket.

For this price the quality is fine, it burns for a short time and goes out in your pocket, but it might improve with use.

For this price, it's a pleasant toy :) However, you need to be careful it doesn't set other things on fire; it's also worth buying an extra insert.
