The oven is described as spacious but the usable space is not that big. The shelves are not as wide as my old oven. My pizza trays will not fit and some of my baking trays do not fit due to the narrower shelf width and rear shelf attachment. I have cooked a chicken in the main oven which took longer than I am used to and still wasn't well cooked. so I don't think the temperature is accurate or even. So far this oven has not performed well. I would not buy it again. A plus is that it looks great in the kitchen, but I want more from my cooker than stylish looks. I want better performance.
