"This stove gets an A+ for durability. It looks like it could take a grenade hit, and doesn't weigh more than a pound or two when filled. It runs on white gas, and one fillup gives you about two hours of burn time.
It burns incredibly hot - I boiled an entire gallon of water in just about 15 minutes, and it was very easy to light.
Downside: no regulator - this baby is obviously intended to be used simply for boiling water. I doubt if you could simmer it very well. (You may be able to make some experiments with pump pressure, I dunno). I don't do much more than boil water for any of my backpacking meals, so this isn't really an issue for me.
And the price couldn't be beat, my father-in-law got it for me for about five bucks at a surplus outlet.
I'd give it a 4 out of 5 for what I intend to use it for. People who need fancier equipment probably won't be as satisfied."
