This microwave was installed in my newly renovated kitchen in February. So far, it's working well. We had a problem with the fan last month but the repairmen found a lot of sawdust in that area which probably caused the problem. No issues since the repair. We use the convection feature more than the microwave. It's handy for baking smaller portions instead of heating up the big oven. The inside (back wall) has been a little challenging 
to clean, and some of the instructions aren't clear, but overall it operates well.
