This is my 2nd Snow Peak GigaPower (both Manual, gave the first one away as a gift), and I couldn't be happier with it. It is near indestructible, throws a VERY hot flame, and has excellent simmer capabilities. Well worth the $$, and the weight in your pack.
One thing to note: the stove itself needs to be run for a bit in order to achieve a stable flame (when you first get it). Think of it as a "burn in" period. If the flame seems unstable in the beginning, just let it get worn in a bit. After the initial burn in, this stove is darn near perfect.
