Review on Samsung Gear Sport Wi-Fi NFC Smartwatch, black by Anuson Chaosuan ᠌

After reading about the importance of heart rate tracking during workouts, I decided to test the information in action with my Galaxy S9+, which has a heart rate sensor. During strength exercises between sets, I tried to keep the pulse no higher than 128 beats / min. (which is normal for my body). Prior to this, the rest did in time for 1-2 minutes. After 1.5 hours of training, I felt that there was no such fatigue as before with the same loads. He returned home with a reserve of strength, and not completely exhausted. Because measuring the pulse constantly with the phone is not convenient, I thought about buying this device. I immediately liked the Gear Sport, they suit me in terms of price, functionality and design, but there are a lot of complaints about the inaccuracy of measuring the pulse. I doubted that the problem was with the sensor, but in the software it is quite possible. I went to the forums on the Galaxy Watch (46 mm) and Gear S3, and there opinions differ. For some, it gives accurate measurements of the pulse, for others it is measured with a large error. There were opinions about the hairline that interferes with measurements, and the thickness of the skin. Based on all this information, I made a choice in favor of Gear Sport, and I was not mistaken. Out of the box, I immediately ated the firmware to the latest version, the pulse is measured quite accurately, the OS does not lag, I work quickly and smoothly. At first, the charge was kept for 1.5 - 2 days, after a week the battery came to life and holds for 3 days. I am completely satisfied with the watch, the only thing I would like is a slightly larger size.
