We have had the Frigidaire 27" wall oven for a month,  after waiting 5 mo the for it to come in at out local appliance center. It's a fabulous product! I've used several of the oven modes with great results... last night I made salmon in the sous vide mode & it was great! The oven has a strong fan that vents i to the room and can get the kitchen hot, but we turn on our cooktop vent to pull the warm air.  I really love it! The size is perfect for my small kitchen.  Installing wasnt difficult because my husband is comfortable working with electricity and the demenions we perfect for our oven hole.  Having an electrician install is recommended. We have a Frigidaire Gallery  induction cook top for 3 years and it was a game changer! It really changes heat setting rapidly.  That too is a terrific product!!  I'll be looking at Frigidaire when we replace our refrigerator next.
