We needed a shorter microwave because the cabinet above our stove was too large and a standard size unit wasn't leaving enough room for us to cook underneath. We actually melted our last one due to the flames from our gas stovetop. It's much shorter inside, but it's about 7" deeper. This is good and bad. It's rough on my 5ft tall wife due to the large shelf that now projects out. She has to use a small step ladder to access the cabinet above it now. This model REALLY NEEDS REAR KEYPAD ILLUMINATION!!! It's nearly impossible to see what key you're trying to push by it's light and a definite no go in the dark. Design flaw. It also makes all kinds of racket. I thought it was defective when it was first installed.
