Advantages: The Watch has a nice clear display and isn't too heavy, the rubber strap is nice and soft and doesn't rub. Charge time is also nice and quick. Heart Beat monitor seems fairly accurate, maybe about 5 bpm out, Pedometer also seems accurate and also displays the calories burnt. Watch connected to my Cubot x9 phone nicely.
Limitations: I also have an Energy-phone pro Octocore that runs on Android, unfortunately even though the Bluetooth connects I am unable to use any functions on the phone from the watch and get an error message when I try to use any functions, so it seems this watch might not be compatible with all modern phones that run on Android.
