Review on Amazfit GTR 2 Smartwatch with Alexa, GPS, and 90 Sports Modes - 14-Day Battery Life, Heart Rate Tracking, and Waterproof for Men and Women (Classic) by Faun Su ᠌

A good and decent model with excellent autonomy and good functionality. If you need a watch for sports, then you need to pay attention to specialized models from Garmin or Polar. But for normal healthy lifestyles or those applying for them - a very good option. Its pros: And they look good and the possibilities are very good. A good choice for everyday use for an active person. With the screen always on, 24-hour heart rate, stress, sleep monitoring and a daily one-hour walk / cardio with GPS turned on, the charge lasts for 3 days. If you exclude anything from this list - much longer. They charge very quickly - about an hour. Large selection of dials. After the last firmware ate, they measure the number of steps very well. There are no deceptions, even if you wave your hand, they will consider everything good. Oddly enough, they work very well in the pool. They themselves determine the style of swimming and the characteristics of strokes, etc. Monitor sleep accurately enough. I have problems with this and they see everything honestly. It’s a pity that you can’t set up a smart alarm for sleep monitoring. But maybe more will be added. Phone notifications work well, but I don't really need it. Tested and turned off. With its cons. Trouble with measuring the pulse. If you want to at least slightly resemble the truth, you need to tighten the strap very much, but all the same, the indicators will be greatly underestimated. Unfortunately, you cannot connect an external heart rate sensor to the watch. They respond well to changes in pulse. But all readings on the pulse must be corrected upwards. I would also like to estimate the variability of the pulse. But this is not stated, although it would be quite simple to do. The control / configuration program from the phone (Zepp) is damp. There are no such obvious options as exporting workouts or sleep monitoring to other applications or a file.
