Why this score?

First Alert Onelink Safe & Sound earns a moderate score due to its impressive integration of smart features and overall ease of installation, providing undeniable value as a smoke and carbon monoxide detector along with Alexa compatibility. However, significant weaknesses, such as limited Alexa functionality (e.g., inability to join music groups) and inconsistent app performance, detract from its user experience. While the device delivers robust performance in safety functions and audio output, the high price may deter those seeking a straightforward smoke alarm without smart features.
