I would buy this dishwasher again.  It cleans well.  The dishes are very clean and it uses minimal water.  The three shelves is something I thought I wanted.  The top shelf for cooking utensils takes up just enough to make my dish loading a little more difficult.  On the other hand I'm able to get dishes done in 1 1/2 hours instead of 4.  This dishwasher cleanse better than my old one and is very quiet.
