Review on 🖤 Gray Bluetooth HRM Chest Strap - POLAR H10 Heart Rate Monitor, Compatible with iPhone & Android by Billy Danaher

really cool device! I've been wearing it for a variety of cardio workouts and outdoor activities for about a week. At first it seemed very convenient to me. Second, it stayed in place every time I put it on, and I swear a lot when my heart rate goes above 135 bpm. Third, I love the fact that it can now transfer/pair 2 Bluetooth devices. Pairing was easy and straightforward. I would highly recommend the Polar H10 if you want to monitor your heart rate accurately. I paired it with a Garmin Instinct. I was surprised that Instinct was within 4bpm of Polar until I was over 145bpm. Good product!
