Review on 💪 Garmin Vivosmart 4 Smart Bracelet - Ultimate Fitness Tracking in Sleek Black Design by Athit Methasate ᠌

Doesn't measure sleep correctly. For example, I didn’t sleep until three in the morning, I watched movies. I remember exactly, because at three in the morning for two minutes the night yellow light of the screen turns off on my computer. But at the same time, looking at the application in the morning, I see that it turns out that at 2:16 I already fell asleep and fell into a deep sleep. It's the same with awakening. I woke up, got up, went to the shower for 15 minutes, and then lay down again to answer messages on the phone, I look at the application, and it turns out that I fell asleep and sleep again, the phase of light sleep. In general, here he does not measure the subtleties, then the question immediately arises of the accuracy of the phases of sleep, since he cannot even distinguish, I just lie on the bed and sit on the phone or continue to sleep.
