This oven was installed by the builder during new home construction so I didn't purchase it directly. The first oven was defective and replaced shortly after closing. 
It's a nice oven and cooks evenly. It would be more functional if the cooking timer started after the preheat instead of before. The way it is now I have to estimate how long it'll take to preheat and add it to the cooking time. I don't know if all ovens are like this. Otherwise I'm quite pleased with it.
