I bought this oven to replace a much cheaper brand convection that had one rack and could fit a 9'' x13" pan, but it was constantly burning baked goods, even if I lowered the temperature 25 degrees.

I was reluctant to buy another Kitchen Aid because a previous one died soon after the warranty expired, but I liked the sturdiness of this oven and the two racks.  

It only cooks convection bake, not radiant bake, but that's not a problem  It cooks beautifully and the food doesn't burn. [This review was collected as part of a promotion.]
