The support products for Keurig coffee makers are called K-cups; which are small plastic cups, lined with filters and containing coffee grounds. A seal is then placed on the cup. Keurig also offers reusable K-Cups. A handle is located on the upper front of the brewer. Once the handle is lifted, the K-Cups are placed in the designated location. When closing the brewer, it punches a hole in the K-Cup. The hot water is then heated and pushed through the k cup to the cup placed under the infuser. Keurig offers a range of brewing systems from single-cup brews to brewers with reserves to hold more water. They even offer a Keurig espresso that specializes in steamed milk. Keurig's suggested retail price ranges from $90 to $200 USD. The company has sold more than 45 million coffee makers worldwide as of September 2014. These brewing systems provide a quick way to brew a fresh cup of coffee every time. (Green Mountain Keurig,
