We bought this oven as part of a complete kitchen remodel. It is mounted above a larger 800 Series wall oven. Here are 4 things to consider when purchasing: 1) I have to remove the door to reach the back of the oven to clean it since the door opens downward. 2) As I had read in previous reviews, the alarm truly is pitiful, to the point of being worthless. I now always use a separate alarm when cooking. 3) When using the unit in convection mode, you lose the convenience of the microwave. For example, when you're baking something in this oven, you don't have a mircowave to melt butter or thaw a frozen item for another recipe. So remember to use the microwave for what you need before using it as a convection oven. 4) A full size cookie sheet will not fit in this oven. 
None of these issues constitutes a major inconvenience to me, and I would buy another one if it became necessary. This oven is still terrific!
