This is a replacement of first, same oven. Which we had used for about 7 years. 
Our only concern is that the TURN TABLE MOTOR holds up. We had to replace the motor 3 times over the 7 years that we had the first oven.
The only other comment is that we wish we could get this oven a little larger, say 2 cubic feet. 
All said, this is the second GE oven of this model in our kitchen so we have trust that this combination oven will perform as we expect.
