I Like it
I've taken this stove on winter mountain overnight hikes in Utah. The self ignite performed well even in cold temperature (0 deg F or below while I was using it) although I always take waterproof matches anyway. I used the stove as my water source and it melted snow great.
I love how small and light it is (there really is no reason to make a stove any lighter or smaller than this) and it performs great. I hike with guys who have jetboils and I don't find myself feeling jealous. P.S. Snow peak says to only use it with their canisters which I think is bunk - I use MSR's and they seem to work fine.
