Installed easily in less than 1 hour, including removal of old unit. All parts fit perfectly. Once it is running, it is quiet, but there is a very loud CLICK once you turn on the power that sounds like something is breaking. I know most sound like that now, but I wish there was a smoother "power on". 99% of houses have dishwashers, and this unit does not come with the rubber boot to marry the dishwasher line - make sure you get one.
