We replaced our old Cusinart Grind and Brew that had a blade grinder with this model that has a burr grinder. The old model had begun to leak water and despite advice from various sources on the internet, I was unable to correct the problem. It was about 8 years old, so it was probably time to replace it.  So far (only in use two days), this model makes great coffee and the grinder is quieter than the old model.  The Wayfair shipping was outstanding, with the unit arriving in only 3 days.
