This double oven seems to work correctly, although I haven't had a chance to try all of the MANY MANY cooking modes. I think the thermostat is accurate, and I like having a convection option. The vent fan is much quieter than our previous double oven. On the other hand, heavily advertising an air fryer mode without including the air frying rack is disappointing - particularly at this price. Also, I would like to control the oven lights separately, rather than having to have BOTH on (or off).  The instructions specify that the oven light(s) should not be turned on while baking - why not?? It would be nice to have a quick reference card for using the MANY cooking modes, rather than looking for information in the thick Use & Care document (which doesn't have an index).
