I've had mine since me and a highschool buddy when to Isle Royale National Park in the middle of Lake Superior back in 2001 for a 11 day trek of the Island. it worked like a charm the whole time, and to this day I have yet to clean, or do any maintenance to it, and it still works like the first day I got it. If only everything else in the world could be made so perfectly. Folds up nice, and stores in carrying case for minimal space and weight. The only thing different, is i have the pre-filled canister bottle version(which we didnt even use up 2 for both our meals, 3 times a day for the 11 day trip), and mine came with a Heat Reflectors, which BC states this one does not? Im sure its not to different.
