I do not have a range so could never buy a frozen pizza. I would buy the small ones and use microwave but they never turned out right. Well I had a credit at a furniture store so today went to pickup this product and tonight put 2 small pizzas in there. Works so great I over cooked them. Oven states 450 temp 15 mins whereas Delisio on package stated 400 temp 17-18 mins. I tried the Starfrit settings and it over cooked them, so next time will follow the pizza makers instructions. This is how strong this oven is. And I could have adjusted the temp but like things a little over crisp anyway so left it as is. It will be fun fine tuning temps/time for various pizza brands and make the perfect pizza.
