Jet Boil works really great if ya just wanna boil water. The fuel can has a tendency to perspire. So if ya pack it up fast its worth tossing it in a baggie first so it doesn't create any rust in the bottom of your unit where it stores.

The trick here is to put the fuel container back into the pot upside down. So that the base of the fuel container is not sitting on the bottom of the pot. You want the narrow end, the threaded end you attach to the stove, to be face down in your pot. Preferably with the little plastic cover still on it.

I've got a slight rust ring in my unit from making the same mistake, I switched to storing it this way, and have had no problems.
