Is a Keurig single-serve machine a good smart coffee maker?

For convenience, yes. The K-Elite earns very high verified-purchase ratings and reviewers praise its temperature and strength controls, while the WiFi-enabled K-Café SMART adds app scheduling and a built-in frother. However, pod coffee is a quality compromise versus drip or espresso, and some r/keurig owners report weak or watered-down cups on certain units.
