Query: Worked for a while

This cord worked for the better part of a year until it just started to give problems, I never really expected much of it but I expected more. The small wires in the connection to the phone are very easy to break and that's what happened to me, it also lost it's ability to retract after a while. It worked great while it lasted and one could argue that I use it more than others because my iPhone needs a new battery but I'm going to try another one.
