I would keep them on hand. I had about 4 or 5 between getting them in xbox live kits, the system, the vision camera, and some other stuff I don't remember but I have already gone through most of them. The wiring in them is crap. I don't treat them badly or anything they just tend to stop working after months of use. You sell them for $4 but when yours breaks you have to pay at the least $15 for a new one. Just hang onto them.
