Product review (1 stars): never buy Bosch
Worst Microwave in my life.
It's broken after ONE year, just after warranty expires. (just like the  the  Bosch $3000+  fridge  I bought )
The cost to repair will be hundreds of dollar ($300+)  but you have to pay because it is built-in.
Never buy built-in, never buy Bosch anymore.

My other cheap ($40)  microwaves works years(or  a decade)  and never broken, I throw them away because of kitchen renovation and my wife wanted a  "built-in" as everyone else does.
