Product review (4 stars): Almost inaudible!
Our 10-year old Whirlpool gold dishwasher smelled funky and was not cleaning well, so we bought this Kitchenaid KUDE70 based on Amazon reviews. It arrived in good shape and installed it myself.  Plastic over the stainless steel prevents scratches during installation. Since there was enough side space, I reused the old dishwasher's insulation to help with sound deadening.  This unit was slightly taller than the previous unit and had to remove its wheels to make it fit in the available space. During operation this washer is amazingly quite as other have remarked.

In use, it seems to clean well but didn't entirely remove everything from a frying pan on the Pro setting.  We are still learning and will try a pot scrubber selection next time.

Shipping took about 10 days to arrive.  Wish the tracking information was a bit better, we knew it was in transit but no other details until it arrived.
