The next potential best Keurig model is the K475, which features a 12 oz brew size and lots of adjustable settings. You can control the temperature of the beverage as well as control the strength of the brewer. With so many programmable options, this strong brewer provides professional-like results. It features a big 70 oz water reservoir, which means you can brew around 8 cups until having to refill it. With a 2.4 inch touch screen display and five temperature settings, this is one of the easiest Keurig models to use. It also features a removable drip tray that makes it easy to clean up.
