The refrigerator is very nice and works well. The only issue is opening and closing the bottom freezer drawer. The rail on which the drawer is running could be sturdier or smoother. It takes some effort and both hands to open and close the drawer. If not pulled or pushed absolutely symetrically with both hands, it will twist slightly and hang up. And even then it is a slightly awkward and requires some strength. I had expected a smoother operation. 
It would be also nice to offer the refrigerator with an option without the water and ice dispenser on the outside of the door like the 800 series.
Overall I am glad that Bosch is offering the 500 series to fit under older existing kitchen cabinets. It saved us from having to buy an inferior model from one of the competitors.
