Review on 💪 August Fitness Trackers with 30 Days of Working Time - App Enabled Smart Activity Tracker Wristband with OLED Display for Heart Rate Support, IP67 Waterproof by Ted Boone

The displayed readings are inaccurate making this fitness watch useless. I ended up using them strictly like clockwork for a while and just uninstalled the correct app from my phone. Pretty good battery life. I stopped wearing them as I don't want to charge my watch every week when it has no other functions. If you run out of battery, you need to pair it with your phone and the app to set the time/date.
