Features and Specifications of the Keurig K40 Elite: Product Dimensions: 14.9 x 12.2 x 14.2 inches ; 13.1 pounds Shipping Weight: 14 pounds Motor: 1500 watt Type: single serve Reservoir: 48 oz removable Drip tray: removable Brew sizes: 6oz, 8oz, and 10oz Method: K-Cups or reusable K-Cup Auto shut-off: 2 hours Suitable For One To Six People Earlier versions of the Keurig K40 Elite restricted you to just one cup size, but now you can choose 6, 8, or 10 ounce sizes. Averaged out, that means you can brew around six cups at a time from the 48 ounce water reservoir. Power and Speed The surprisingly powerful 150” watt motor makes possible the exceptionally short time required - 15 seconds - to reheat the water between brews. Variety and Flavor If you love K-Cups then this machine is for you. With many varieties of hot drinks to choose from few people will fail to find their favorite brew. The K40 Elite can make you tea or hot cocoa if you prefer. You can even have iced beverages. Just fill your cup or glass with ice cubes and brew as you do normally. Once you've primed it before using it for the first time, then the K40 is very easy to use. The water reservoir is removable (as is the drip tray) for cleaning and re-filling with water. If you ever forget to switch it off, the auto shut-off will do it for you after 2 hours. The descale indicator will tell you when descaling is required. This is a big plus, as descaling is an important part of the overall maintenance and cleaning process.
