This Muurikka D-300 gas burner heats up rapidly and the power is easy to adjust. The diameter of the burner is 30cm. The steel windshield is sufficiently large, so the flame is not likely to go out. Heavy pans are no problem as the burners are sturdy with strong long legs. Legs can be removed for storage. This burner is easy to set up and can be used as a portable cooking device.
