First of all, the appearance is very beautiful, very out of the young people's taste, with this watch to school, my friends asked me where to buy this watch, functionality, they have a lot of features, gps movement track, bluetooth call, a variety of health monitoring, i like this watch, i prefer bluetooth phone this function, sometimes really convenient, do not need to put the mobile phone directly on the side of the watch, the logistics is also very fast. It didn't take long to receive the parcel, the logistics is very good, very satisfied.
