Couple things about the Jetboil
- The coffee press has presented problems when people have chosen to "press" when the water is still boiling. Not suprisingly, this can lead to a "massive boil-over" and likely burns. In other words, don't push the plunger down when the water is boiling. I believe Jetboil is working on printing instructions in bright orange on the press for future purchasers.
- When storing a cansiter with the burner in the cup, put the burner on top of the canister. If you put the canister on top of the burner, it can push the "hook" of the Piezo down onto the burner, causing problems with ignition.
- Troubleski's suggestion of water on the canister is a good one. MSR has also suggested creating a "bath" of water around canisters to help the fuel burn more efficiently at colder temps.
