In addition to its wonderful cooking features, this GE Profile double wall oven with Advantium technology (PT9800SH9SS) is easy to operate!  The laminated QuickStart Cooking Guide that is provided is also very helpful.  The Advantium reheats, and cooks many foods in its preprogrammed options.  It cooked a frozen pizza well, and even toasts bread - so I got rid of my old toaster oven!  The wall oven combination looks great in my kitchen and matches my GE Profile french door refrigerator.  Although I've only had it for about a week, I look forward to many more years of satisfying use of my Advantium/ Convection combination wall oven!
