Purchased to replace our first Cuisinart Coffee on Demand coffeemaker which was around ten years old. This new model has a water filter and detachable water reservoir. It makes great tasting coffee just as the older model did. The only thing that I have notice that doesn't seem right is the gauge that shows the level of coffee. It seems to indicate a full reservoir until I have only a half reservoir remaining. Matter of fact, I hear the audible signal telling me my coffee is ready so I'm off to get my first cup of the day.
