This model replaced a previous GE wall oven we had for nearly 30 years. Tech sure has changed since then! I very much love how much more evenly it bakes than the old one, and the convection feature is to die for. Bottom oven worked well also.  I had a hard time getting the phone app going, but once it was online It wasn’t hard to use. Overall it is a very good oven. I am very happy with it.
