Query: burnt outside, mushy inside

I'm surprised at how much praise this pizza oven has received. I have made two fresh and 1 frozen pizza on mine and have been dissatisfied with the results on all of them.First of all making a pizza from scratch is so hard, I wanted to give up at that point. How do they get the crust to be an even thickness?Second, the pizzas cooked terribly, esp the fresh ones. I followed the suggestions <cooking bottom first> but the inside of the crust was so mushy no matter what I did. The bottom crust was burnt, the cheese and toppings burnt, the inside crust mush...yuck!Even the frozen rising pizza came out similarly. I should have stuck with the oven. Plus this is so heavy and takes up so much space
