This dishwasher is very quiet and cleans way better than my old GE Profile.  The reason I liked this one so much, is because I have harder water but haven't purchased a water softener for the house yet.  This has a built in water softener that will hopefully help the racks last much longer than our old GE Profile's racks which rusted out within in a year.  The salt seems to last a good while as well, but I also didn't need to have the hardness level up very high as it's set right in the middle.  It was very convenient that it comes with a way to measure the hardness of your water in order to set the dishwasher softener accordingly.  It is slightly smaller inside, but nothing that makes me regret buying it.  Very quiet and super efficient as I can only tell it's running when it drains the water.  The dishes come out sparkling clean every time and have never needed another cycle to get clean.  Very pleased with this purchase.
