Product review (1 stars): I would rate it worse than 1 star if I could!
This is the most expensive and worst oven I have ever owned. The service people are trying to tell me that it is normal for the temperature of the oven to fluctuate 30 degrees. Cookies burn up on the bottom and are raw in the middle. Weve ruined a prime rib roast  the bottom burned up and the inside was raw. It doesnt matter where you put the rack in the oven. It goes from 375 to 450 for no reason. Then you also have to deal with the middle plate and no where to store it when you want to change it to one oven. I have baked for years and was known as a very good baker until this came into our house and the place we bought it from won't do anything about it but keep recalibrating with no good results. DO NOT BUY THIS OVEN!!!
