Excerpt: I chose this because my rough opening is EXACTLY 22 inches and BRICK. If you have a bigger opening or new construction, there might be better choices. The controls are simple enough and it heats quickly, but the fan is noisy and stays on long after you turn the power off. If you eat in the kitchen, you'll be listening to this racket. If you install this yourself, watch for sharp metal and, in my case, loose screws on back.
Summary: This wall oven was installed as part of an overall kitchen remodel and has been the most disappointing feature of the whole project. It is not intuitive to use, and the manual is not very helpful. It seemed to be at least 50 degrees too low the first few times we used it. After searching on the Internet, we found the instructions for recalibrating it, but the maximum possible increase is only 30 degrees.
