It cooks well enough that you'd always find something useable unless it's torrential rain and you'd get used to carrying a few bits of dry flammables with you. The size of thing makes it not very suitable for backpacking though. It's great to have in your open boat, van etc though.
I have the version of the MSR pocket rocket which Alpkit sells in the UK. I'm friends with the founders so often buy from them and their equivalent is half the price of the MSR. They sell good functional kit [1]
