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

The device has proven itself only from the best side, it measures the pulse perfectly, I use it with the official application, many different workouts for every taste, it is very convenient as a personal trainer, it shows all heart rate zones depending on your training goal and health status, you know when to speed up and when to slow down , a very comfortable strap does not fall off when running, I have not tried swimming yet, although I plunged into the water with it, everything is fine the device is alive, as soon as I start swimming, I will definitely add a review
