We replaced an 8 year old version of the same basic model.  The new unit works well and is very quiet, but has a couple minor glitches.  The lower rack does not glide out easily onto the door.  The cycle light in front is hidden by the counter overhang, so I occasionally open it when it's running.  If the light was on the top of the handle it would be visible when standing at the counter.  The control lock feature is good since the touch pad can be easily activated when opening or closing the door.  

We installed the unit ourselves, which went well with one problem.  The front bottom kick panel is screwed in and is difficult to attach.  Why not just use friction or spring snaps?  It would have saved 20 minutes of frustration.

Overall, we're very happy with the dishwasher.
