We just built a new home and I'm so glad we chose the Advantium versus installing a double wall oven, which we would only use a few times a year. Right now, it's just my husband and I and the Advantium is a great alternative to use rather than waiting for a traditional wall oven to preheat for smaller meals. There are so many heating options! I was very impressed by the "sensor" reheat option, best leftovers ever! If you are considering doing a double oven, definitely check out the Advantium as a second option.
