Man-o-man I truly live this K-Duo Coffeemaker. We have never had a single serve option that the K-Cup system provides and it is a game changer in my household. We love coffee but don’t always want a full pot. Now I can have one to get the day started and another in the afternoon as a little treat. Then when my wife and I are on the same schedule or we have guests we can put in a pot and offer some delicious coffee to all. The button system is incredibly intuitive. The options for cup (oz) size or number of full cups is great. The tank last for a while before needing to be refilled. So it’s just maybe 3 steps and boom great tasting coffee. It also has a feature to brew a cup of iced coffee which accounts for ice in the cup and dispenses the perfect amount to integrated with melting ice. Love this one
