We've had one of these for over a year and we really like it.
Does a better job of cooking pizza than anything else we have.
We also use it to cook other frozen foods. French frys, pizza rolls, mini egg rolls, onion rings, chicken nuggets, chicken strips and cheese sticks and many other frozen foods that come in fairly small sizes.
We also have an American Harvest Jetstream convection oven that does a great job on the crust but because of the speed of the fan, even at lowest speed and at lowest elevation, blows the toppings off the pizza and makes a real greasy mess of things so we didn't use it very many times before giving up on it for pizza.
