Product review (5 stars): I've had it two years now - this is a really impressive Dishwasher!
We've had this dishwasher for two years now. We have had zero issues with it, and it's pretty remarkable. It's extremely quiet. You do not hear it running unless you're literally standing next to it. It seems to use steam and heat really well to loosen food. I've never owned a really good dishwasher before, and have been pleasantly surprised to find that I can put really dirty dishes straight in without intensive rinsing or scrubbing. We have a small home with two people, so the 18" size was an awesome way to save some space in our kitchen. My wife and I run it once a day, and it keeps up with our dish demand perfectly. I'd expect that it would be enough for a family of four if you ran it twice a day. All in all, it's very well made, and we couldn't be happier.
