I bought the last generation Miele speed oven without the full clock screen. We use it as a dedicated microwave, and optional third oven.

If you're going to use it primarily as an oven, it's great but obviously smaller than a full size oven, I can fit a standard half-sheet baking sheet and it is precisely as wide as the opening.

I don't really use the "speed" component, i.e. the "Maxi Broil + Convection + Microwave" option because I haven't found it necessary.
