Another Bosch fan here. It was the fourth dishwasher I had in seven years, and it has lasted three years and still is going strong. Incredibly quiet and cleans wonderfully as long as you use rinse agent. I didn't use rinse agent at first, and my dishes were not clean -- even food was not removed -- but the rinse agent made all the difference.
One thing I wasn't told when I purchased my unit was that Bosch dishwashers (at least the low end ones I was considering - between $500 and $600) don't have a dry cycle. I found everything still dries as long as you let the dishwasher sit closed for about an hour or so after the cycle ends. Also, my model has a much smaller capacity than the junk dishwashers I had previously -- I was told it is the result of having the steel tub. While the steel tub takes more room, it is the reason the dishwasher is so remarkably quiet, and having had incredibly loud dishwashers, I would rather do more loads and have the quiet operation. Honestly, this Bosch dishwasher is one of my favorite possessions -- nothing but Bosch for me in the future.
