The pizza oven works great, I still have not made one from scratch but cook Pappas Murphy's in it a lot. Makes great cookies, garlic toast and about anything you would make in the oven in the house.
Mine stays on the deck year round. I keep it covered and have had no rust issues. Once a year I cover the burners well and take my pressure washer on low to clean it. Best outdoor cooker I have ever had.
