Review on Heart rate monitor Polar H9 black M-XXL by Anastazja Adamczyk ᠌

I bought a sensor for crossfit classes (3 times a week) to see how much I “run down” on heart rate in complexes. Pairing with the Polar Beat app, sound notification in the headphones, complete training information, and a wide variety of workouts make this sensor very attractive both in terms of price and functionality. I've been using it for over a month. I recommend to buy, statistics \ analytics tren, och. useful information for an athlete and just a person who monitors his health. I use Phone (Android 11) + Polar H9 in conjunction. While everyone is happy, all statistics and online training are displayed on the phone. The sensor itself does not interfere with classes, does not tighten anything, there is no discomfort. I am satisfied with the purchase, I consider this device useful and necessary, it is up to you to decide whether to buy it or not, but I will say that it is better than a watch for 40 thousand and much better than a lot of fitness borohol on the market.
