We purchased this range three months ago - white black matte knobs and handle.  We love the smooth burner to burner cooking surface, ease of cleaning, excellent burner temperature control, roller oven rack and over all look is beautiful.  This is a dual fuel unit so we are just learning how to use the regular baking method and convection method of using the oven.  So far it works excellent and cooks evenly. 

There is only one negative and that is the lack of lighted burner knobs when a burner is in use.  The flame can be turned so low, you might not notice it is turned on and forget. This is not a quality or performance problem, but we purchased the black knobs and handle set.  When the unit was delivered, we received a box with the black matte set in addition to the standard set on the range.  This is a huge waste since there is nothing we can do with them.  GE would not let us return the original knobs and handles.
