Review on Polar H10 Bluetooth Heart Rate Monitor, Compatible with iPhone & Android - Black Chest Strap HRM by Amphai Nanthaklang ᠌

Didn't pay for itself at all for the 5.5k I spent on it! For the functions performed, a regular xiaomi bracelet for 1.5k would be enough. I have not changed the battery yet, but for such a price there should be batteries with recharging. I regret spending so much money on standard features. Pros below: There are no advantages, somehow it performs the declared function. Has cons: I bought it to measure the pulse and mileage during football and running, but it doesn’t work at all without a smartphone nearby. 1. No built-in GPS 2. Appendix: there is some analytics, history, calculation of averages, trajectory, but I expected more. 3. I slept with him to measure the night heart rate - it didn’t work, it turns off or just stops counting after a while, or it’s just not designed to record low heart rates. 4. When running, sometimes it does not record heart rate for unknown reasons, then errors are obtained when displaying analytics. Distance accounting errors also occur, but this is probably a smartphone issue. 5. I wanted to measure my heart rate while playing football (to hell with it, with mileage - I won’t run across the field from smartphones), put it on the podium, didn’t move further than 25 meters from the smartphone - nothing was recorded. 6. Very expensive for such a weak set of somehow performed functions.
