I recently purchased a Bosch Benchmark dishwasher.  I'm simply amazed at the quality, performance, and low sound level of this machine.  When my wife and I shopped for this appliance we looked at all the major brands.  The Bosch design came out on top for us because of the classic style and the clear top-of-the-line performance noted in the reviews.  After owning the machine for several months, I can say that all the reviews that call these Bosch machines the best are true!  The dishes come out perfectly clean and shiny regardless of how dirty they started.  Such great performance and we don't hear any sound from the machine.  This model projects the cycle time on the floor in front of the machine.  If it wasn't for that feature, we wouldn't even know it was running.  I highly recommend the Bosch dishwashers.  I can't think of anything they could do to improve the product.
