The carafe side of the brewer works fine and makes good coffee. However, the warming plate temperature is too high. It boils the coffee in the carafe. (You can see and hear it boiling.) This leads to a burnt taste after it sits awhile. The K-cup side has some serious design oversights. First, you cannot easily see how much water is in the reservoir. Second, there is no easy way to drain or dispose of leftover water in the reservoir. You must unplug the entire unit and dump the water out in the sink. A removable reservoir is a must in a product that only gets occasional use.
