Good item !
Advantages: Smartwatch is well made with good quality materials. Case is made of REAL brushed stainless steel, it is strong and very well finished. Dial is made of REAL glass (not plastic), screen resolution and colors are pretty good. Micro-usb charging socket is well protected by a dustproof cap. This watch has many useful functions and can be easily paired with almost all smartphones equipped with bluetooth 2/3/4, however few functions (anti-lost) cold not be available for some devices (bluetooth 2/3). Strap is very strong and stylish and in the box i also found an interchangeable strap. Hearth rate sensor is fairly accurate. The battery will last approx one day and can be charged in about 1 hour. The price is cheaper than the quality of this item (i'ma satisfied of this purchase), i should only like an application (apk) update to ensure greater compatibility.
Limitations: Software applications (apk) for Android devices are NOT fully compatible with all smartphones, i have an old Zopo ZP980+ (Android 4.2.2) and i found some difficulties to find/install the right one for my phone, however, all main functions are guaranteed (only remote camera and anti-lost funtions are cut off).
