This replaced an older KitchenAid dishwasher. Although not bigger, it does hold much more. Also, it is quieter and has a number of features that are significant improvements, eg. Silverware shelf, adjustable racks and shelves, no heating element, opens when done and light indicate it is running.
So far, all indications are positive.
The only confusing feature was picking this one out of over a dozen similar Bosch dishwashers.
