Love that it was economically friendly. Ordered 2, app is easy to use and it records data accurately. It's fun to use and reach your daily targets become a fun daily competition. It's easily set up and setting your personal targets is easy. The battery lasted 6 days and I use it 24/7 to track steps, treadmill and workout. Absolutely recommend this product .. compared it to a friend's Fitbit and actually like this better and the app is very user friendly. Only negative is it doesn't link to my Samsung health app.
