I have a small kitchen and this unit acts as a second oven.  It's also great to use the oven on hot days or if I have a small item so that I don't need to heat the big oven on the range.  It has a smaller clearance requirement than other units so it fits in a smaller space than other units.  It has a larger interior which allows larger dishes in it for cooking.  I made a pie and it came out perfect.   It even has a "Warm" feature.  The only negative is that the controls are a bit confusing, but I am getting used to them.
