When shopping for wall tent stoves, the first thing you should look for is one that has a compact design. This way, you will not have problems carrying it even when you are traversing some of the most difficult trails outdoors or even if you are actually scaling mountains and climbing huge rocks to get to your destination.
Secondly, make sure that the wall tent stove you do choose has a reputation for excellent reliability. It is not the type that will give up on you after several times of use. Anything that is likely to have problems with reliability or durability should be immediately disregarded because it could literally place you in danger of starvation in times of emergency outdoors.
Thirdly, make sure that the wall tent stove you purchase is easy to use. Make sure to test it beforehand and find someone to demonstrate its full capabilities for you before buying.
