Query: Good idea. Poor longevity.

Bought this item in 2008 to connect an iPod touch to a port on my car audio system. Worked pretty much as advertised. But after very infrequent use (once a month maybe), I started noticing recently that only one channel was working (right speaker only). The issue is that a wire had become frayed at one jack-end. So it is now useless. These did not receive rough treatment. The issue seems to be the very thin gauge wire (20 I would guess), which may be good for retractability, but turned out to be bad for durability. So I am back on Amazon now shopping for a replacement. (As a side note, the mechanism to retract the wire isn't exactly easy to use -- it usually takes a full tugs to get it to work right, like a pull-cord on a set of cheap window blinds).
