Fulfills exactly what it should !!

Benefits:
It requires much less wood to eg. Water to cook as with nem campfire
One can almost everywhere a fire with the box to turn on what a campfire is not possible
The box can be fired with a Trangiabrenner or with solid fuel
Low weight and pack size
Processed entirely of stainless steel and clean

Disadvantages:
Acquisition costs (campfire costs nothing)
Can not be stored immediately after use because it is still hot (cool but pretty quickly)

Conclusion:
Can the Bushbox recommend any of a small practical outdoor stove investigated.
This is the way to the "Version 3.0". This comes with the pictured pot supports for smaller pots and pans
and you can with a Trangia spirit stove combine perfectly what the water Cooking time (0.5 liters of water in 5 minutes with no wind)
makes very short.
