I bought this item in September to replace a worn out Ninja oven and I am sorry I didn’t just buy another oven.  It has to be preheated where the other oven did not.  It will not sit still on the counter. Every time you open or close the door it slides. It burns foods on the bottom.  The door is in the way and if you aren’t careful you burn your arm.  I hate this item and would not recommend it. I’m sorry I wasted my money and I’m ordering the oven I loved as I use it every single day!
