I bought this in the box, but the box was opened, I can't return it. It works poorly. I tried making papa murphy's pizza in the lower oven and it was done, almost over done on top and the bottom was doughey still. So frustrating. I made rolls in the top oven and they were baked differently all over the pan. I make a lot of bread and I can't rely on this oven to do anything accurately, evenly or up to temp. Even on convection settings. I am going to sell it as-is for next to nothing and start over with something reliable.
