10/20/2022 I bought a Polar sensor on my arm. I work out on the street to smear my chest with water in winter under a chest sensor and then lie with inflammation in the hospital, not for me. The pulse shows almost the same with my Honor watch, the difference is 1-2 beats. VoMax 2 units. Chinese did not take even though it is cheaper. Today I trained in it during my workout (1 km), the Nike pulse program announced only once its average value, as I later found out in the application, the difference with my Honor watch reached 14 beats, and the distance was 300 m. Two programs out of five I connected through ant+ worked incorrectly. Namely, in Polar flow, gps did not turn on during the entire training session, and Adidas did not record the training data. This sensor will not replace the output of the clock during training, but will only record the training and its data as a voice recorder writes a speech. I turned on the recovery program in the Polar bit while I put on the equipment, she repeated to slow down the pace and the whole workout too. And Polar flow again hung gps. About a year later, voice prompts appeared, I recently bought myself a chest pulse sensor from China and decided to compare them during training, the difference during interval walking was approximately 3-11 beats, roughly 5-10 seconds of delay, in principle, tolerable, but the chest sensor gives a big load. But in it, unlike believe the sens, you can’t swim and it’s more convenient to wear a sensor on your arm than on your chest. Also, believe the sens can be connected to two devices at once, unlike the Chinese chest pulse sensor.
