The Ratio Six is a well designed coffee brewing device--except for the carafe. For those of us with mild arthritis of the hands, that carafe is trouble. The pouring lid requires a firm grip to tighten properly, but there are smooth edges to it, making it difficult to grip and align. The pour spout sprays fluid in a wide swath, even when held in the recommended position. The upper lip of the carafe body makes it difficult to get the last few ounces out of the carafe. My wife and I spent more time cleaning up spills than we did drinking the well-brewed coffee. Those problems with the carafe led to me returning the machine.
