The product has worked well so far.  The only issue I have is that the light under the knob on the left front burner doesn't go off when the element is turned off.  We have to work it back and forth for the light to go off.  I want to make sure it goes off so that I can ensure the element is turned off and doesn't cause a fire.  All of the other lights under the knobs turn off immediately when the knob is placed in the off position.
