We love our Ziola pizza oven. I had my heart set on a wood fired pizza oven but we can't have that where we live so to find an electric oven that cooks at 500c was the answer and we are amazed at the results. We have only used the Biscotto stone thus far at temperatures between 370 & 450c and had some great results. I say this as a novice to pizza making, as I had only used a domestic oven before. This is a game changer.
