Hello Saw there was some discussions earlier on CCS re world smallest silent burner.The Radius 437 burner is a strong contender for first place.Will use it for a project on a Radius 21 tank. When checking the Catalogue section here I see that Radius used this burner for 1 pint collapsible stoves in the 20s 30s.With this burner on the R 21 I can use the standard potlegs.When comparing this burner with Radius 537 burner I see that burner top is similar. But 437 burner tubes are thinner and this burner will only fit rising tube #2014. Please see photos.brgds Bjørn
Hi again The temptation was too great.I mounted this 437 burner on the tank, lit it and one less virgin burner in the world.Burned great and got my small Trangia kettle to a boil in a few minutes. brgds Bjørn
WOW,great flame-pictures of "UFO"-burner!! wish you could add a sound effect. The sound of these are magical! /Klasse
Hello Yes it burns very well. I like the name UFO burner Klasse. I use mainly the bigger cousin Radius ( or Høvik ) 537 and have never experienced underburn. Isn't that a nice feature on a silent burner. Merry xmas and a happy new year Bjørn
