I have been using Nike Plus for a little more than a month. I loved it until it didn't log my run. I ran with it, got home, plugged it in to download my info and it wasn't there. I know it had the info at one time because it gave me my stats at the end of my workout.
So I thought, well I must have done something wrong. Yesterday it did it again, only this time it locked my ipod up in the middle of my run. I had to restart my ipod completely and all info was lost.
I'm not a person that complains, or throws a fit if I get bad service. But this is very frustrating, because I really enjoyed the product. From what I understand this doesn't happen to everyone, but I have run into a couple others with the same problem.
In my opinion it's only 30 bucks, it's worth taking the chance.
