While the Sense 2 offers excellent health monitoring, some users find the integration with Google Health Premium a bit limited initially, and the smartwatch features are less robust than some competitors.

While the sensor accuracy is generally good, some users report that the battery life doesn’t quite match the extensive feature set, requiring daily charging.
