Since I bought my cuff I can not do one without a jogging. Now I can bring my phone with me. So I can listen to music, or call in an emergency. I downloaded the pro runstatic application that gives me all possible information about my races: course, average speed, velocity curve, distance, etc ... But I needed to use an armband. The touch function correctly even in the pocket, neoprene perfectly protects the phone from sweating. By cons I have not tried in the rain but I think he is not doing it for.
