Great Stove, relaiable, no maintenance.
The universal canister attachement is great for traveling (in South America) where you dont alway have threaded cartiges available. I have been very happy with the stove performance and was surprised by the BPL reviw where it scored pretty low.
It IS a heavy stove in those days of ultralightness, but the size of the burner allow efficient heating of big pots an pans. I mostly used it inside my tent (*BEEP* me) with a 2L MSR Titan pot.
It is really easy to unscrew the burner head from the main "pipe" (by hand), alowing a minimal volume for strorage.
The long folding handle is easy to manipulate with mitts or gloves.
My latest use was on a 25 day expedition on Mt Logan (where most people use liquid stove). We decide to use canister stove so we could cook in the tent, no matter the weather. It proved a VERY good idea since we where storm bound for 3 and 5 consecutive days, where outside cooking would have been impossible. We use the Ascent hagning kit wich worked also very well. In order to optimize efficienty I built a custom wind breaker form light foil. It prooved to efficient: we partially melt the MSR heat exchanger on the pot and melt the piezo lighter. Our gaz consumption was slightly less than 1 canister for 2 people per day, boiling 14 L of water from ice or snow.
I had a really hard time with the piezo (from working once in a while to not working at all) in freezing temperature and also at high altitude (3500m +, in Peru, Equator, Argentina, Yukon and Alsaka) whatever the temperature...
