I haven't used my regular oven since I got this awesome toaster oven. I have used the following functions: Toast, Bake, Broil, Speed Convection. I found that the oven maintains the temperature very well. Here are some of the things I have successfully made using this oven:
*Spaghetti and Meatballs
*Frozen Pizza (used the pizza stone that comes with the oven)
*Brownies
*Toast

The pizza was a bit messy as it melted onto the wire rack and the pizza stone. It was difficult to remove from the pizza stone even though I preheated the stone as directed. The directions say to use only water to clean the stone, and it was difficult to get the crust that stuck to the stone off. I may not use it for pizza in the future, but everything else was great.
