bought to use with Cisco devices for console access. Installation was easy. I had no problems with this cable. My old cable caused a blue screen. This cable has not caused any problems. I would recommend and buy again. Quick Tip: As with most Cisco console cables, the RJ45 end of this connector won't have a hard time breaking the clip. I keep a plug on the end of the RJ45 when I carry it around. It would be better if they put a clip without a hook.
