Review on POLAR H10 HR Sensor: Bluetooth Enabled, 🏋️ Black, M-XXL – Advanced Accuracy for Heart Rate Monitoring by Agata Dmochowska ᠌

Zero reliability. Pros below: Doesn't fly off the body. Convenient. There is a native program on a smartphone for displaying workouts, which is quite understandable. Bought to control heart rate and calories burned. Its cons: After 2 years, it broke down, stopped showing the pulse, even on a new battery. For the price, I'd like good quality. Not disposable sensors. Having tried all possible ways to reboot and changing several batteries, now I can only throw it away. Maybe changing the belt will help but not sure. My understanding is that the warranty is no longer valid. Not all simulators are connected via bluetooth.
