I had the 30" version of this cooktop in my previous home.  I used it every day for 9 years and had NO issues with it.  I was so happy with it that I decided to install the 36" version in the new home we just built.  This cooktop is awesome...it looks very sleek, it is super easy to control the heat; the dual burners provide a lot of flexibility with pot and pan sizes, the warming burner is wonderful.  Mostly...I love that the cooktop has no handles to clean around!
