The first time, the magnetron failed, and the service guy said it was common with my model.
The second time, was microwaving the babies milk for 40 seconds, and the microwave glass just shattered.No idea why, but, it must have been arcing to do that .
Don't like the bosch controls that much - visitors often have to ask how to use the microwave as it is not obvious.
But, apart from the break downs, and the controls are no problem if you know how it works, the actual oven itself is pretty good.
Miele might be better if price is an indication though.
