Review on Amazfit GTR 2e Smartwatch with Alexa & GPS, 90 Sports Modes, 24-Day 💪 Battery Life, Heart Rate & Blood Oxygen Monitor, Waterproof, for iPhone and Android - Grey by Bao Ha ᠌

- Autonomy and fast charging. I have enough charge for 7-8 days: AOD all day (turns off at night), sleep monitoring with breathing tracking, several SpO2 measurements per week, periodic heart rate measurement, constant notifications (I do not turn off the Internet on the phone). Without all this, calmly 2 weeks and more will last. - Convenient magnetic charger. I connected it to a PC, magnetized it to the case, and when I need to charge it, I hook the clock to the charger with a slight movement - Appearance, quality of materials. Nothing superfluous, cool strict design, high-quality materials, bright screen, rich colors. No scratches in two weeks. The watch looks good on my thin hand. The ideal screen size for me and the watch itself. - The accuracy of the heart rate monitor. Compared with Polar and Mi band4 watches. - SpO2 measurement accuracy. Compare with a pulse oximeter.​ - Price. - Sleep monitoring. According to my observations, sleep tracks well, but sometimes it does not catch small awakenings. Able to track daytime sleep. It is comfortable to sleep with them, I do not notice them on my arm.
