Another one of the 12oz brew size Keurig models is the K575 Keurig, which comes with some extra features. For starters, it provides hot water on demand and features a platinum, contemporary design that suits any décor. The machine is fully programmable and allows you to control the strength of the brewing process. The removable water reservoir brews 10 cups before needing a refill while the machine supports K-cup sizes from 4 to 12 oz. The reservoir is easy to fill up when you need to do so and the large touch screen makes it easier to control the settings.
