No need to fire up the big oven. This little rotating pizza oven cooks frozen pizza fast. No preheating required. Top and bottom element with rotating pan. Cooks pizza evenly . Also great for take- and-bake and fresh homemade pizzas. No need to preheat the oven. Great for Home, Office, RV, dorm room, etc. There is a small scratch on the pan, which can be seen in photo. This does not affect the functionality of the unit. *Though not recommended by the manufacturer, I always lined the pan with aluminum foil for easier cleanup.
