I have used it as an convection oven numerous times and as a microwave. Only cons, the door opens like a regular oven and it is installed above my wall oven, I am short and worry about burning myself on the door, and I will use it as an oven then want to microwave something while it is still hot. Depending on what the item is and what it is on, I may not be able to microwave the item. Planning ahead is important.
