We had another brand for many years that was repaired numerous times because it took a long time to warm to temperature and didn’t maintain an accurate setting. This wall oven has been great since the first day. It warms quickly and cooks to perfection. It has so many usable options, we keep the manual handy as we try new methods. The microwave is a dual convection and will heat to 400 degrees in a few minutes saving energy and cook time. We bought the optional air fryer rack. This unit alleviates the need for small appliance air fryers that clutter the counter. It has a beautiful clean modern design that compliments the kitchen. Great buy!
