We've only had this unit installed and running for a couple of weeks, but this has been long enough to see that works well- easy to load (adjustable height top rack is a great feature), holds a lot for an 18 inch unit, and washing/drying performance is very good.  You do have to be mindful to not put items that have a small opening and a tall inside in the four corners of the top rack- these don't get enough wash water projected into them by the upper washer arm.  We put bowls and other shallow items in the corners, and it does great with these. The door is a bit flimsy, but it shuts securely.  Installation was very easy except for the water line hook-up.  The T fitting tightened facing in a bad direction, making it very difficult to line up the water line-- there was interference with the plastic casing of the internals of the dishwasher.
