OONi pizza oven is a great innovation which makes genuine Napoli pizza go to every family easily. But you need to turn the pizza manually every 10 to 20 seconds. More often than not you will over burn one size even to charcoal. Now a motor driven turn table frees your hands and guarantees even baking every side. The motor is 12 V DC. 3 pieces of rechargeable battery 18650 can be used for a week for every overnight recharging.
