Poor quality control - Trangia Multifuel Burner

I bought this stove, and tested it cooking some home fries and eggs. During the cooking of the eggs, the stove failed - a round piece that was I think spot-welded fell off and the stove went from blue flames to yellow. So I think the quality control for this stove is not sufficient, especially for such an expensive stove. I returned the stove.

However, I liked the way it fit into my Trangia 27 cook set. But I also didn't like that you can't adjust the flame enough to simmer.
