Fantastic design! Performs like a champ at moderate altitude (9-10,000 ft) & cold conditions (20-30deg F) & strong winds (20-30mph). Very neat and clean design which is hassle free and frustration free to operate and packup- even with your gloves on. Yeah, it has no simmer, but for backpacking food- who cares? We keep around a Whisperlite and skillet for car camping when our cooking gets more ambitious.
