So far, so good. We love the overall flat top - don't have to lift a pot to shift it to another burner.  Tried out the quick bake feature which works as advertised.  We used a double burner griddle over the middle burner with no problem.  I really like the easy-to-remove burner grates of which there are three. Just set them aside & you have access to the entire burner tray for cleaning. Very glad we made this purchase.
