Delivery month. Track to track. Sensor charging does not remove the percentages, and changes color, because at first did not understand how much charge. The alarm is working with a bang. Pedometer work is not, but it was necessary to me. Camera is so-so. Control the camera phone adequate, but it can not run if the phone is locked. By BT and запущеным application for music player sound is a watch, it is not convenient, or I figured out how to make that sound was a phone, and tracks the hours clicking. Sound if talk by BT through watch so-so, to hear. SMS read perfectly and вайбера and ватсапа No. Charge with the included BT and without SIM card is enough for a day without BT third day go and not even a hint of севшую battery.
