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

Broke down very quickly. For half a year! Accuracy of measurements - I began to lose my pulse for several tens of minutes in a row, it shows a resting pulse that changes plus or minus a little while running, which is very funny! I stopped connecting to mobile applications like Adidas and Polar, although the bluetooth sees it. It helps to remove the battery every other time, reset the settings and connect everything again, but it already infuriates. It continues to connect normally to the harmines on the arm, but as mentioned above, you run for several minutes without understanding the pulse and the averages simply fly down significantly. An absolutely unreliable device has become for any conclusions about training. The Polar website does not provide any help except for the banal ones - buy an electro gel (I bought it), wet the electrodes (urine), pull out the battery to reboot (I pull it out :))))
