Review on Smartwatch Amazfit GTR 4 46 mm Wi-Fi, Superspeed black by Mateusz Grzesiak  (M ᠌

All the same, this is more of a fitness bracelet than a smart watch. But in general, for training, this is a quality thing. Got pros: Bright display, many functions and preset workouts, navigation is nimble and accurate. The charge lasts a long time. Pair with a bunch of adidas running, strava and more platforms. Has cons: After 140 beats / min, the pulse begins to overestimate greatly. As a result, all PAI analytics, etc., turns into just a beautiful picture. I had to buy a chest cardio sensor separately.
