We needed an "open bottom" model due to the way our home was built years ago.  We were relieved that Bosch made such a model.  We do wish they had a step-up model with the 3rd drawer, and a little better drying option.  The inside of the machine tends to stay wet.  We prop the door open just a little to take care of that.  The machine cleans very well, and, of course, is amazingly quiet!
