We've had this cooktop about 3 weeks and so far, we love it.  I've only cooked on it a couple of times, but like how easy it is to adjust the temp.  I am not a chef, or even much of a cook, but I knocked off one star because it really needs 2 large burners.  My husband has used it several times and no complaints from him, so it's a winner.  My favorite thing about this cooktop is no knobs to keep clean!  It looks so sleek and shiny and is a breeze to clean (I use the special cleaner after each use).  Happy with this purchase.
