Just 2 of us drink morning coffee, so one side is filled with my favorite flavor, and the other contains my husband's favorite. So easy on those dark and sleepy mornings to instantly see which kind is which, without fumbling through a pile of all of our K-cups (other flavors are kept in another container). The carousel is slim, lightweight, spins easily, and takes up very little counter space. Design is attractive, and it coordinates perfectly with our brewer! Holds 30 K-cups, 15 on each side - very easy to see the contents and to refill as well. Of course, it would work just as well filled with every flavor of K-Cup you have on hand!
