We bought this oven after lots of research…including building our own. I have owned this for 1 year and I am a chef. The oven is large (larger then any other models on the market). I have roasted back-to-back trays of chicken wings, whole chickens, pork and leg of lamb. The depth allows you to cook for large groups. If you’re in need of clear how-to-build directions, look to youtube. Not only is it beautiful to look at, it’s stainless steel surface is easy to clean. And it is mobile, allowing us to move it as needed to meet entertaining needs. We make amazing pizza! You’re wasting your money when considering the look, convenience and efficiency of this superb pizza oven.
