Mr.
Advantages: Clear screen, Comfortable fit and feel. Looks good. Speaker volume loud and clear. Voice microphone on phone call is reported to be clear, adequate volume and no distortion or background noise received. WiFi picks up signal very well. All downloaded apps work. Battery life is adequate for my use, a full day of minimal use. Easy magnetic attached charging cord. Google Voice responds better than my Cell Phone. Works great as a stand alone. Its a little computer on your wrist.
Limitations: Screen response sometimes lags. Occasionally will have to swipe two, three or four times. Can not think of any other at this time.
