I am thinking of getting an external Heart Rate Monitor such as the Polar H10 because my workouts are sometimes between 6-8 hours of running and thus the battery drains quite quickly. I read on Amazon and other forums however, that the Apple Watch and the Polar Heart Rate Monitors don’t get along so well (e.g. losing connection).
Are there any users here, using their Apple Watch with Polar Heart Rate Monitors that can share their experiences?
