We've had this dishwasher for over three months.  It was so hard to get used to not having to prewash dishes!  Seriously, we scrape off the big stuff and put the dishes in.  Everything comes out spotless.  It's amazing.  And with our old dishwasher we only ran it when we went to bed because of the noise.  This model is so quiet I can stand right next to it and sometimes I'm still not sure it's running.
