Product review (2 stars): Thought it was better...
.I bought a superboil replacement knob and I was pleasantly surprised to see that the outside was actually real stainless steel instead of having that plastic overlay which buckles up, I was very happy UNTIL a short time later I realized it had the same cheap plastic sleeve which turns on the burner. It broke pretty quickly and I was again left with a useless knob! I don't really complain but it makes no sense that a high end appliance would have parts that are made so cheaply and would not look to fix this problem quickly after so many reactions to this issue.
