We love the single serve side although he water tank could be a tad larger, say 50% larger. The brew/carafe side is a bit more challenging. Buttons on that side, their purpose and how they operate is confusing and instructions are not straightforward. Its taken us some time to figure out. (I normally "get it" right away when using new appliances. My spouse does not. That's why we gave it a 3-star rating.) Overall, we like it. It makes coffee. We would buy the same unit again.
