i had the dishwasher put in after much comparisons. it preforms so quietly you have to look and listen twice!!. but, the cleaning ability is extraordinary, and the toughest bake on particles, the greasy mess  and the spot less glasses are uncomparable to  ANYOTHER  brand..  a stainless steel interior will insure many years of life for the owner.. i was impressed to see a third shelf for flat pieces which i didnt find elseware...
