Burning Off the New "Made In China" Tent Heater for Camping

I really like the pretty shadowbox design, but will it actually radiate enough heat to matter? Breaking it in over a can of Sterno. It really needs a more secure base to prevent it from falling off the canned heat. The lid could be used as a base for a tea candle or a smaller alcohol burner. Will definitely give that a try next time. This setup is functional, but not very secure.
