This dishwasher replaces an older one, which was a difficult (smaller size) to replace without renovations.  This unit fit in perfectly with no adjustments needed. We have followed all of the operating instructions, and our dishes come out perfectly clean and spot-free each time.  This dishwasher does not have a lot of features that larger, more expensive models have, but it does have numerous cycle settings.  We DO recommend rinsing chunky and dried on food off before placing in the dishwasher if they are going to sit and dry before washing.  Great quality for the price.
