We recently upgraded our 3 year old GE dishwasher to this model and I'll say it doesn't disappoint. Aside from it's modern and clean finish, it cleans beautifully. With its 3 pull out cleaning trays, there's more than enough room to squeeze lots of dishes, glasses, utensils and other items in there reducing the number of loads over the lifetime. 

Compared to our last unit, this one is super quiet. Our kitchen is hard wood flooring and the master bedroom is just a few feet away and I can hardly hear the dishwasher when running it before bed, even with the door open. 

The big question...should you pay for professional installation? I have very limited "handyman" experience and I had no issues installing this unit. I'd purchase this unit again in a heartbeat.
