I received this K-Duo Coffeemaker from Keurig and Influenster in exchange for my honest opinion. This is by far the best coffeemaker I have ever owned. Whether you want an iced coffee, a hot mug or a whole pot, this does it all. 
It is very user friendly and even lets you know when more water is needed. I don’t know that I could ever go back to using any other machine. The brew times are speedy and the drinks are delicious. I have nothing negative to say about this machine. It’s simply the best.
