This unit doesn’t work. It cuts off preheating 100 degrees less of what it was set for. Took another 20 to get to the right temp. After putting pizza in oven it went down to 350 instead of 400 that it was set for. Then it stopped rotating and pizza was burned in back of oven and pizza wasn’t done in front of oven when it was on convection. This is the second oven they sent me that doesn’t work. I won’t put it on selfclean because too many people said theirs quit working completely when self cleaning.
