We had survived for many, many years with the GE wall oven that came with the house, never considering a replacement. However, after 27 years it finally gave out. So, we replaced it with a GE, and could not believe what we have been living with (and without) all these years. This wall oven is sleek, very easy to use, and seems so much more spacious than the "knob" wall oven of the past. A great appliance.
