We had to purchase this combo to fit our cabinets.  Microwave door comes down in front, NOT to the side (like the last one) which makes it impossible to wipe splashes on the back and top of the microwave. Glass turntable vibrates as it turns. Cooling fans run for a long time AFTER food is done so it is confusing to hear the beep to alert you food is done.  Oven takes forever to preheat. Also design is strange in that when it is installed it is not flush to area surrounding it (not cabinet).  There is 1" gap in front of oven/micro unit and the doors, so I had to fabricate a piece to fill in the gap.
