This oven has been tested and works perfectly, heating up quickly and maintaining convection airflow. However, it has cosmetic dents on the metal casing. Specifically, the back-left corner housing is crunched/bent inward near the bottom edge, and there is warping along the lower metal lip. This damage is strictly cosmetic and does not impact the inner baking chamber, the door seal, or the functionality of the power cord. All 4 rubber feet are still intact and the unit sits level.
