This was very easy to install and replace our old dishwasher. I would say about an hour tops. The three racks come in very handy which the top rack even has its own sprayer. I will say the dishwasher is pretty quiet compared to any other dishwasher I have had.  I never knew what I was missing until this dishwasher and it’s the app- I love that you can control it this way.  If you want the best dishwasher- look no further. Definitely worth the money.
