## Customer feedback

Customer feedback highlights perceived accuracy, ease of use, comfort and connectivity, including reports of pairing with Garmin watches and Kinomap. Experiences with functionality and battery life are mixed, with some reports of the device turning off or charging problems. That variation matters if you rely on the listed long battery life or need consistent operation across a workout. The overall rating distribution is mixed, so aggregate ratings alone do not establish how well an individual unit will perform.
