Double oven replaced an old single oven. The New oven accommodates wife size cookie trays and no turning of trays is needed for even browning on all sides of the trays. I love the pull-out rack, the convection feature,  the temperature probe and the bread proofing and keep-warm functions. I haven’t tried the steam clean feature yet, but it seems like an energy saving feature that should make it easier to keep my ovens clean. The timer alarm should be louder, it is very subtle on the hi setting.
