I do not regret this purchase. The show (which runs on Android Wear), once connected to the phone and bluetooth with a dedicated application, vibrates to tell me the arrival of incoming calls, SMS from my and my mails. Super convenient to work. No speaker on this watch (can not take the call directly on the watch), but that does not bother me. The driver's voice or using the touch screen very good. There are too many things to say about this watch, then go on the net reading tests. To summarize, it is not so big as this, autonomy is correct (about two days) for this kind of article, and makes good service. And I like his side sport, and the fact that we can change the dial when you want, according to his mood. I really recommend.
