The dishwasher is very quiet you can hardly hear it when it is running.  The install was a little bit difficult due to a drip pan below the unit.  The sheet metal and the clips holding it in place are not heavy enough gauge.  I had to align the clips so it would stay.  (NO TOOLS NEEDED)  If it were heavier it would be better.    The middle spray arm is a bit low and catches on taller items in the silver rack.   Overall a great addition to our dream kitchen.
