The BOSCH 500 Series Over-The-Range Microwave we just purchased is a definite upgrade from the 25 year old microwave it replace.  It is very stylish, quiet, modern, and easy to operate.  A set of simple instructions on how to use the machine was given and is readily available to handle to do the "once in a while" microwaving we may do.  The basics are a easy to do.  I would highly recommend this model.
