I mistyped my shipping address but Cables Unlimited corrected the problem immediately and re-shipped at no extra cost. They provided great communication and cooperation. When the ZipLinq arrived, it worked fine. I use it to connect my MP3 player to my car stereo. ZipLinq provides a secure connection at both ends, it is easy to adjust the length of the cable and the sound quality is excellent. The retracting cable works smoothly and it makes storage easy and convenient. I hope it lasts a long time.
