This Dual Oven is a space and energy savor.  To heat only half takes barely 5 minutes so my pizzas are ready to go quickly.  I usually let it stabalize for just a few more minutes to make sure to not burn the top of my items if using the top oven.  It does take some getting used to because it cooks different on the top or bottom oven.  Also this is a convection oven so even heat.  Overall I like a new feature every time I use it.  The timer is unique and requires you shut it off, but better than my old one which I never heard.  The cooktop is clean, provides multiple options for different burner sizes.  Overall A+ on this unit.   Planning a kitchen remodel around this unit now. :)
