After weeks of testing, the Garmin Index Sleep Monitor proves to be an ultra-comfortable, accurate sleep tracker that integrates seamlessly with the Garmin ecosystem, potentially replacing the need for a bulky smartwatch at night. While its single-purpose design excels in delivering detailed sleep metrics, the $170 price tag raises questions about its value for users already invested in multi-functional Garmin watches. This dedicated wearable could revolutionize bedtime routines for fitness enthusiasts seeking uninterrupted rest and precise recovery data.
