The Ninja Espresso & Coffee Barista System is compact and versatile. It can brew coffee grounds in nine sizes from cup to carafe, hot or cold. It can also brew single-serve espresso capsules, espresso or lungo. It has a lot of convenient built-in features. It has an adjustable espresso cup tray, a removable water reservoir, and used capsule storage. It’s not compatible with K-cup pods, which I find useful when I’m in a rush. Overall, the system works great, is easy to maintain and I’m really enjoying it.
