Conclusion: Bought mine 6 years ago. It was top-rated, convenient and easy to use. Then today the display showed H97 - apparently a fatal error. I threw out 2 cheap microwaves when I got this only because they were too small, but both lasted twice as long and still worked when I got rid of them.
Conclusion: For what's meant to be a premium microwave oven, our family got approximately two years of use out of it before it suffered the killer H97 error. As was the case for many other owners of this model, it was actually less expensive to replace it than have it fixed.
Summary: I had its little brother, the NN-SD697S (1.2 cu ft) CONs: ~~> The knob is a hassle. I thought I'd like setting cook time with a knob, but it's not as quick or easy as tapping a keypad. This microwave has no numeric keypad. Setting cook time is the main event.
Summary: Very poor ergonomic design. The door cannot be opened unless you push the large button firmly, making single handed operations virtually impossible. The stupid dial used to set the time and cooking values severely limits the values you can enter.
Summary: We're another victim of the H97 error code. Loved the microwave for 5 years, but expected it to last longer for the price. From other reviews, it looks like we were lucky to have it last that long.
Design flaw will prevent operation after a few years.

Summary: This review is (again) moot, as the models of microwaves changes so quickly, but I'll record it here for posterity. This appliance has a significant design defect: the internal flange that holds the safety switches for the door closure is too thin, and bends every times the door is closed.
