The Keurig B40 single serve coffee brewer, with a 1500-watt element, produces either an 8 oz or 10 oz quality cup of coffee in less than a minute. The automatic shut off feature will save you money by shutting the machine off after two hours of idle time. The descale indicator lets you know when it is time to descale your machine, helping prolong the life of your coffee brewer. Keruig has a large variety of hot beverage choices available with its wide selection of K-Cups. In this video, Zack and I will give an overview of this versatile single-serve machine.
