Silk about six months in my possession and I must say I am very satisfied all in all! I like the design very good, simple yet classy! But I use them less than "SmartWatch" such as a conventional clock ... The radio ions I can only say that I do not think bad the call function, but this is useful only in conjunction with a headset. It is better if the clock would have a speaker and microphone integrated would .... the SMS function I find wirderrum really great! when I'm traveling by car, it is pleasantly short to see who wrote what and without the phone having to dig out of his pocket! Music on your phone Play WORKS Unfortunately, if you look at Music Unlimited logs: Real shame !!!! Unfortunately, Facebook does not yet function as it tells me andauernt I had to log on to the main unit, but what I have done ... I have to deal with it probably something more .... But at the end I'm very happy and I would buy me anytime again !!!!
