Also great points!
Untested gear is always a concern- I don't want to think about how many times I have learned too late that something was just not going to do it's job properly, or that I should have practiced before using it.
Megan and her friend also had an incident years ago with a Mini Trangia that could have left them both very badly burned. She has never used the Mini Trangia since, and suggests that no one else use one either.

She has since turned to more compact versions of the OP because it's easier to tell when it's burning. The roar of the pressurized gas helps a lot when it's really sunny and you can't see a flame.
