Review on Polar Vantage V2 Smart Watch: A Sleek Black Fitness Companion by Thu Hang Bach ᠌

The watch glass is strong, I have already checked it. It also saves that the glass is deepened into the watch case by about 1 mm. Before buying, I analyzed the need - NFC and receiving calls on the phone are not as important to me as the need for health analysis. The oxygen saturation sensor on the watch is not very important for me, for this there are medical devices that accurately measure the oxygen saturation in the blood, and the level of perfusion, without measuring the latter, it will not be possible to accurately measure the oxygen saturation - when the hand is cold, the data will be incorrect, the perfusion level will show this . Music tracks are switched - in principle, it is enough if the phone is with you. I compared the pulse with a chest sensor - they measure very similarly, a delay of about 3 seconds, which is very good.
