Feedback based on monitoring the following sports: - classic skiing; - strength training in the gym; - swimming in the pool 25m; - run. I use it in conjunction with Polar H10, except for the pool, because the Bluetooth signal does not pass in the water. In water - monitoring using a built-in optical sensor with a tightly fastened bracelet. In general, I am very satisfied with the purchase, I wear it without taking it off. I train 3-5 days a week. I charge about every 3 days.
