This is one experience I had cooking a frozen digorno pizza my dad left for me when they had to go out of town for a week and I stayed and watched over his house for him. I was alredy high off of some good stuff, They have a oven and it's all digital, I get it to come on warm up so I figured ok it's working I come back 17-20min later and my pizza is cold. damm ok so I tryed again same thing, so I threw it away. damm I hate digital ovens..
