Ninja Coffee Maker Black
Score: 77/100Rankings
The Ninja PB051 is a versatile single-serve brewer that handles both pods and grounds and includes a built-in frother, making it ideal for specialty drinks. Its trade-offs are a modest water reservoir and plastic construction. Best suited for solo drinkers or small households seeking flexibility in a compact unit.
The Keurig K-Café SMART adds Wi-Fi, a built-in frother and a large 60-oz reservoir to the single-serve lineup, delivering café-style drinks at home. Its bulkier plastic design and need for frequent cleaning offset the convenience of its many features. Best for coffee enthusiasts who want latte capability and smart control in a small household.

Everyday users consistently praise the speed and quality of lattes, the convenience of a large water reservoir, and the range of brew options, but they frequently mention confusion over dimensions and the need for regular cleaning of the frother and reservoir.
