The combo microwave oven works well. My complaints are minor. The buttons are hard to select and the cooking temp of the microwave is lower than my older one so making adjustments there. Not sure why I would ever need 3 racks in the oven as there is very little space for food if you have all 3 inside. If you use the broil feature, place items on the lowest shelf or turn the temp down by at least 100 degrees or your food will char quickly.
