Review on 💪 Enhanced Fitness Bracelet: M7 - Pressure, Heart Rate, Call Notifications, Sleep Tracker - Android and iOS Compatible (Black) by Vn Ti Dng ᠌

I don’t know for sure whether it’s like that for everyone, or just me, but the pulse measurements differ extremely significantly, as do the pressures: when measured with a tonometer, 100 beats, on the clock 72. The pressure also shows 120/76 at 140/100 . on the inside the glass is scratched, possibly due to this. The box is crumpled, the feeling that this bracelet has already been returned, I was even afraid that it would not turn on. So I will issue a refund.
