Today was the day I was starting my Nike+ challenge runs for Lilla's (Lilla: Self-fulfilling Prophecy) challenge. I was immediately frustrated. I had problems right away getting my wristband to see my sensor. It just wouldn't synch up and start recording.
I looked through the http://www.nikeplus.com knowledge base and saw some ideas to try. None of them worked. I called their support line (amazing but they were open on a Sunday) and the gentleman tried quickly to help me but was unsuccessful. He told me to return it.
I went back to 24 Hour Fitness and returned the item and got a new one. After charging it I headed off for a 1 mile run just to test it out. Immediately I faced more frustration (but caused by myself). As I was running the USB portion flew off the wristband. I stopped and put it back on (but the time is continuing to run). I ran again and got to about a 1/2 mile and looked at the wristband and the USB thing was missing again. I had to walk back and find it. Finally I noticed that there was a place to secure it into its slot. After securing it, I never had another problem. However, it definitely added about 90 seconds to my run.
In addition, all the stopping and starting stressed out my right calve muscle a little bit. I rubbed that down though.
