This is my second 5160 model. The last one lasted about 10-years. I purchased the same model because of the good life as well as existing wall brackets making for an easier installation. The one thing that slowed installation was that GE moved the front screw locations that hold the microwave up against the cabinet. This added an additional half hour to re-drill holes in the cabinet but would not be an issue if this was a new installation and not a replacement. The only problem I had with the old microwave was the cracked white plastic molding surrounding the door.
