We were fairly limited in which double wall oven would be able to fit in our existing cabinetry. We were intrigued by the GE fit guarantee and decided to purchase this oven to replace a dated GE oven. Overall happy with it. However, our biggest issues with it is the preheat time and the timer volume. It takes a totally ridiculous amount of time to preheat. Really inconvenient for last minute meals, etc. the volume is really quiet on the time timer. That’s more just an annoyance.
