Old dishwasher died so had to buy a new one.  After reading reviews decided to give Bosch a chance.  It is so quiet the only time I hear it is when it drains.  The 3 shelves and middle shelf that raises up and down mean I can load it and run it once a day in a seven person household.  The dishes come out sparkling and the plastics dry.  Only downside is that auto cycle takes three hours, but worth the wait.
