It heats and cooks as expected.
The 'Done' ding volume is much too soft. (The High and Low volume settings are about the same, too low). In addition, the fan contiues to run after the microwave completes and 'dings'. Consequently, it is  hard to tell it has stopped.
The microwave is above the Bosch oven, and its' door is hinged on the bottom. So, it is difficult to reach the back of the microwave for cleaning. 
Considering the variety of microwaves available this Bosch has poorly implemented standard features, a diappointment.
