Strengths: Good basic running watch functionality such as good display and controls for lap timing etc.
Weaknesses: The battery life is so low as to render the watch almost useless. The links between the components are unreliable and frequently cut out. The speed measuring is sometimes wildly inaccurate even on the rare occasions when all components appear to be working together correctly.
Overall: I have returned the watch to Nike for repair. They offer no receipt or reference number you can use to trace the item - I've sent it back purely on trust. If and when I get it back and the above defects are corrected, I shall post another review. Otherwise, give this watch a wide berth.
