We love these ovens and the ability to have Alexa preheat any of the ovens and the convenience of having it work wirelessly with the notifications.
We did not buy this oven, it came in the house we just had built. One issue is that the vent will vent all the heat out of the bottom below the lower oven. So when you are cooking you get the nice smell of food, but also all the heat from the oven as well.
This is a nice oven, very sleek looking, and with several features. The number 1 reason for purchase was the GE fit guarantee. I replaced an old GE wall unit and this GE unit fit perfectly.
