Keurig K-Express Essentials vs Keurig K-Duo Coffee Maker

Buy the K-Express Essentials if you only ever brew one cup at a time and want the smallest, simplest Keurig on the counter. Buy the K-Duo if a household, an office or guests need a full carafe some mornings and a pod other mornings. The K-Express is a basic single-serve machine with a fixed reservoir and few options; the K-Duo adds a 12-cup carafe side, a shared 72 oz reservoir, programmable auto brew, strong brew and brew over ice. Owners rate the K-Express higher (4.4 from about 65,000 ratings versus 4.1 from about 7,200), but the K-Duo does far more and is the better long-term pick for anyone who brews for more than one person.

• Choose the K-Express Essentials if you brew one cup at a time, want a compact machine that fits under a cabinet, and do not need a carafe or a timer.
• Choose the K-Duo if you regularly brew for two or more people, want a 12-cup carafe alongside pods, and value programmable auto brew and a larger shared reservoir.
