Sump'in ain't right. I have never, ever upset a pot using a Trangia, or other burner, for that matter. I favored the Trangia especially for SAR, when you wanted to heat something up, and you didn't want to fiddle with it. You put the water on to boil and then tended to other pressing matters. In really wintry condition, you carried a SVEA or some other liquid gas gadget. Heat right now,and plenty of it!
