Review on 💪 Amazfit GTS 2 Smartwatch with Alexa, GPS, and Fitness Tracking - Men's and Women's Waterproof Watch for Android and iPhone with 7-Day Battery Life, 90 Sports Modes, Blood Oxygen Monitoring, and Heart Rate Tracker (Black) by Yoonki Baek ᠌

Pretty good watch, the pulse oximeter works, measures correctly, checked at work using specialized equipment, but measuring this indicator on the watch is quite problematic, with the slightest movement of the hand, the measurement is reset, and the lack of movement does not guarantee you the result the first time. You can talk on them, it is convenient while driving, the sound quality is very good! The pedometer works with an error of +/- 6-8 steps per 100, when compared with MiBand 3, at the end of the day the difference turned out to be 700 steps (less on the GTS). It is convenient to mark workouts, the pulse counts with an error of 7-10 beats per minute (which, in principle, is not bad for non-professional equipment). As for the battery, with minimum brightness and constant heart rate and sleep monitoring enabled, it eats up 20% per day, I would like this figure to be less, of course, but in comparison with the same apple watch, this figure is much better. In general, I am satisfied with the design and functionality, although a bit expensive!
