This unit replaced a simpler Bosch dishwasher that we had for 16 years with only one repair call that entire time. This 300 one is quieter, fits in the same space, and cleans better than the old one, no question.
The thin top silverware shelf is fantastic. Using that, we don't need the basket and can fit much more than the old one on the two other shelves.
Bosch is a top rated manufacturer and we have never regretted purchasing their units. We will be buying Bosch again. Eventually.
