The Keurig K10 Mini Brewer makes a single cup of hot coffee in less than two minutes. The system uses the K-cup packs, and it is ideal for small spaces such as dorm rooms and vacation homes. This system allows users to brew coffee in three different sizes, and a removable tray allows the brewer to accommodate larger travel mugs. The brewer has a built-in energy saving mode that prompts the brewer to turn off after 90 seconds, and it has a reservoir capacity of 10 ounces.
The K10 Mini Brewer is very easy to operate. Users simply pour the desired amount of water into the reservoir, lift the handle, place the K-cup pack, then push the handle down. A single button operates the device, and once it's pressed, the brewer does all the work. Reviews for the Keurig K10 Mini Brewer range from 3.8 stars out of 5 stars at Bed Bath & Beyond to 4.1 stars out of 5 stars at Kohl's.
