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

Acquired for long enough wear, in a dream, to measure the variability, and not just to use during short sports activities. Disappointed completely. In those support devices stated in plain text that "Polar equipment is hygienically certified. Why wear at night? Perhaps you have an allergy? And you know, yes, I'm really allergic, allergic to stupidity. Immediately begins irritation under the boobs. It’s a pity that I noticed this late, I didn’t want to return it at first, and I didn’t attach importance to redness. But it's too late, I can't return the goods. Tech support is great, yes.
