I got this stove right when it came out directly from Snow Peak and I am completely in love with it. I also own the MSR Pocket Rocket and this stove blows it out of the water. It smaller, lighter, and puts out more heat than the PR. I have only been able to use it once on a three day backpacking trip in Arkansas and it performed flawlessly. Excellent simmer capability, relatively stable platform, and solid construction makes this a must buy. I don't know how it behaves in windy or cold conditions, but canister stoves in general don't work amazing. I can't speak to the fuel efficiency of this stove, but it still seems like I have a fair amount of fuel left after cooking for 3 other people in Arkansas. I would recommend this to anybody who is looking for an ultra-light stove.
