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

Happy with the purchase. I use it for cross-country skiing, rollerskiing, running and strength training. Works great. It's a pity that neither the device nor the Polar Flow app has a battery level control. With modern miniaturization, a battery could also be built in. In the application, you have to turn on gps all the time, start the workout and turn it off right there, because. I almost never need this information. But why the pulse is not measured without gps, this is a big mystery. So far I have paired only with a Samsung Galaxy Note 2 smartphone via Bluetooth, everything always works fine. There is a real lack of the ability to start recording a workout in the internal memory of the sensor from the sensor itself, without using a smartphone. Or at least the ability in the application to cut out unnecessary pieces at the beginning and end of the workout (when the recording is started, but the workout has not yet begun or has already ended). The belt is comfortable, rubberized, adjustable. When properly dressed, it never falls off or moves out, even with a variety of intensive work on cross-country skiing. The sensor is almost invisible even under very thin cross-country ski suits.
