Review on CANWAY Portable Wood Burning Camping Stove - Windproof & Anti-Slip Stainless Steel Backpacking Survival Stove With Bag For Outdoor Hiking, Travel, Picnic, And BBQ by Yiorgos Reynolds

Very simple design, even simpler to use. Boils covered water inside of 5 minutes, heats cast iron to searing capable temperatures. Perhaps one day they'll make movable vents to adjust the size of the flame, but for $20 shipped, this is the kind of device that should be going out in pallet loads for humanitarian aid missions. It isn't the smallest stove out there, but it's ungodly efficient for its size and weight.
