This is a fine little machine and it produces authentic restaurant style pizzas, though a little experimentation with temperature and timing is needed to suit your dough and the thickness of your pizzas.
But be warned! If you are producing fulsome pizzas with a good topping of cheese and maybe a slosh of olive oil, it's inevitable that you will have some spill-over onto the stone. You'll probably notice nothing out of the ordinary the first time you use the machine. But the second (and subsequent) times, no matter how carefully you scrape the stone after cooking, you will discover that you have imported a smoke generator into your kitchen. Our solution is to preheat the oven outside the back door until the last session's soaked-in oil burns off - our neighbours always know when we are cooking pizzas!
Potentially more serious is the fact that the handle which opens the top of the clam-shell is situated on the front of the machine. This machine gets ¬very¬ hot inside - well above the temperature of a conventional oven. If you open it with an unprotected hand while the machine has a pizza inside, the lid directs superheated steam onto your hand. I now use a silicon oven glove, which is instantly covered with water when the lid is opened. I would certainly never leave this oven switched on in any area where unsupervised children might have access - the thought of what might happen to a child with a face at around table height is a little scary.
But for all that, after years of adapting to a conventional oven, this little device cooks the finest pizzas I've ever made. If that matters to you, live with the drawbacks.
