Review on IP67 Waterproof Smartwatch: Android and iOS Compatible with Call Function, Heart Rate & Blood Pressure Monitor, Sleep Tracker - Perfect for Women and Men by Jon Delgado

This watch exceeded all my expectations. The phone needs to be fully charged before use. Download the app with QR code, quick and easy setup. The battery lasts a long time, it does not need to be charged yet, a week has passed. No need to buy an expensive sports watch, buy this one instead!
