I have moved from a Wahoo Heart Rate monitor and this thing is an absolute beast in comparison. Firstly the chest belt this comes with is much better quality, I guess you pay slightly more for the premium. It stays on at one place and does not move even after a heavy workout. I do a lot of HIIT training so having a chest strap really helps in that regards.
The monitor itself is amazing in terms of maintaining connection to whatever it is connected to. I use it with a Garmin Fenix 5X watch, but this can easily connect to your phone through the polar app and a bluetooth connection. Would definitely recommend others to try this monitor on.
When it comes to accuracy and connectivity, the Polar H10 heart rate sensor is the go-to choice. Monitor your heart rate with maximum precision and connect your heart rate to two Bluetooth training devices of your choice simultaneously.
