I was skeptical about this product because some reviewers said they had trouble maintaining temperatures/cooking. However, we have found it easy to put together, get up to temperature, and cook with. It will lose heat quickly if you do not maintain the fuel, but this was to be expected. It's not a sit-it-and-forget it kind of thing. We've made pizzas, steak, and chicken wings in the pizza oven, all with great results. Just be sure to turn the pizza often or it will burn on the side closer to the fire. Overall, you can't beat this product for the price. If you have experience with grills/smokers you will have no trouble learning how to use this pizza oven.
