The bowls make an impeccable impression. The Brenner looks visually from right dibasic. Unfortunately, he does not work as it should. Aligns to the flame vertically downwards, it goes out. For other burners that is sometimes the case; but only if the flame burns only briefly. In this burner it goes out even if they are allowed to burn previously a minute or two. Thus, the burner will only work with an inclined posture, yielding sooner, sometimes the countertop heated as the Desserschälchen! It is beyond me how a well-known manufacturers can bring such a bad design in trade.
