Review on Kingwear Smart watch KingWear DT3 with bluetooth call (Black metal strap, black case) by Micha Maciejowicz ᠌

I took it only for hours and notifications. However, I tried to take a chart of the heart rate during the day, when measured once every 10 minutes, the batteries last for 3-4 days. It measures quite accurately. Sleep parameters are taken from space, I can just sit and he starts to think that I am sleeping. Sleep only works from 9 pm to 9 am approximately, if you sleep before lunch, then part of the sleep falls out of the schedule. At first there was a big problem with the constant disconnection from the phone, but resetting to the factory settings seemed to help, I didn’t notice it anymore. The function of turning on the display with a wave of the hand works crookedly, the display turns on when it wants, the battery lands be healthy. In general, the watch for this price is not bad.
