Cooks bottom and top of pizza not done

I love this thing! We have an efficiency apt with a tiny kitchen area. I have used this for pizzas, "Just egg" fritatas, frozen beyond burgers,tots, veggies, quesadillas, and more. It is my most used appliance next to my coffee maker:) It is so easy to use and clean. It does get hot on outside so be careful around kids,pets & curtains. There is no temp control. The green light comes on when it' done preheating same as a waffle maker.You just have to keep an eye on whatever you're cooking. Haven't burned anything yet. Pizzas come out perfect and quick.
