Review on POLAR H10 HR Sensor: Bluetooth Enabled, 🏋️ Black, M-XXL – Advanced Accuracy for Heart Rate Monitoring by (seo joon) ᠌

For half a year it worked fine, and then it started, then the pulse falls off, then the pulse freezes, then the pulse drops to 80 and stays at this level for several minutes! Replacing the battery did not save. In general, it was wild to see from the polar, there is also a Chinese sensor with Ali, so it works much more stable of this vaunted polar ! I also read reviews about it, watched reviews, supposedly the coolest sensor, as a result, wasted money !
