We just moved into a new home that is ten years old, and the dishwasher included was the basic builder level appliance.  I thought I was just loading it wrong or not cleaning my dishes enough before putting them in, and getting use to it not cleaning everything.  When we installed this I was blown away at how a good dishwasher actually works!!!  I can put in completely caked on dirty dishes and it comes out spotless!  My favorite feature is the way it dries the dishes by popping open the door, I make my kids put away dishes and they love that they don't have to towel dry the dishes anymore!  This is super quite which is a great feature for open plan layouts.  My husbands favorite part is the upper silverwear level, it is pretty amazing I must say...  Good Job Samsung!
