I own one but haven't used it much. Figured it might be good to have if the power goes out so I can charge a phone. The grill attachment they make for it is real cool
The tin can, and this stove are a "rocket" type stove that does a hotter cleaner job of burning because of the way it focuses air draw and fuel. it directs theheat to where you need it. Rocket type stoves can be built out of nearly any material, dirt, brick, tin cans, pipe, etc. all of those do a better job than a trational fire.
I have boiled a LOT of water and cooked a LOT of mountain house and oatmeal with this stove. Weighs just a few ounces, solid fuel so no sloshing bottles or fuel spill issues. Cheaper 'n dirt, available everywhere for 5-8 bucks. Had mine for well over 10 years now. Have a MSR whisperlite that I rarely fool with, as I prefer this. It fits inside my nesting pot/pan set. Easy to make a wind break out of any available materials at hand. Just perfect for backpacking or pack-in hunting. Sometimes I think we spend too much on making life too difficult...
