First time experience with an oven unit with all the bells and whistles -- so still on a learning curve -- but thus far everything has performed wonderfully.  Always wondered whether a convection feature would be worth it  and the answer is a resounding yes!! All of the features I have used thus far work easily and am very satisfied with this product.  The aesthetic of the oven in stainless steel and black-out function panel is also very sleek and has updated my kitchen's appearance significantly.  Even my neighbors say they wish they had chosen my new GE appliances when they did their remodels.  I would recommend this product line wholeheartedly.
