Very good product, the smart alarm clock is a marvel it allows me to wake up in great shape and will not wake your partner or your partner view that it is a vibration that will awaken you during your light phase of sleep. For activities it is very good with Lifelog application. The applications for the control of certain functions (photo, music ...) Attention however new models Sony products I'm so captivated by the current and Lifelog has my opinion in view of the addition on the SmartBand Talk and the SmartBand future are higher where it 4 stars. Anyway my only regret is perhaps not having taken a newer model to enjoy more things.
