Have found it an awesome little performer.

Uses (I think) about 120g of gas per hour. A cannister lasts about 2 hours total burn time.
I can heat a pint of water to boil in about 7 minutes. So I easily get 3-4 days cooking (3 times a day) e.g. Freeze dry meals, hot drinks, noodles etc.
The entire setup including cannister weighs just over 300 grams (About 1/2 pound.)
Works for me. Reliable & had no ignition problems.
