Four star only because of the hassle of having to have the oven installed twice. Replaced an old GE oven with this new one. Original oven did not work out of the box! The electronic display kept displaying the message “configuring your oven” but the message never stopped. My dealer delivered a new oven the next day, which worked perfectly. After using the oven for about a month, it is great. Cooks evenly, is easy to use and has some good features my old oven didn’t have. I really like the slide out oven rack, makes it really easy to place large or heavy things into the oven.
