We built a house in 2013 and have been using the dishwasher that the builder put in every since. We recently went from that dishwasher to a Bosch 500 series and we couldn't be happier. Our previous dishwasher, which is a brand I won't name, was so bad that we hand washed dishes for the past year prior to getting our Bosch. What a great start to the new year having the best dishwasher - we couldn't be happier!
