Features: Supports Bluetooth connection and allows you to use health management and other functions via the dedicated "GloryFit" app. I was using it as a pedometer. I bought them to use as a pair, but one was used for nearly six months, and the other was mostly just sitting at home. There are no scratches, so I can't tell which one was used more. There is only one charger. There is one replacement band. How about it for smart watch beginners?
