We bought this because we wanted a built-in microwave in combination with a convection oven.  The Advantium line intrigued us and we decided to try it.  Using the microwave is a bit tedious, having to click and turn knobs several times before it starts.  The lower oven is noisy when in the pre-heating convection mode and seems to take an unusually long time to pre-heat.  Otherwise, it does a fine job of baking the few things we've tried in it.
