I think I got a defective cable reel. Short runs, 10-30ft, work great, long runs, >50ft, have been a nightmare. I've had to double up almost every cable I've routed. It seems that sometimes the cable has a kink as it uncoils, and if it does, you can bet this length of cable won't work until you've cut that kink. This is an issue when you need longer runs. It took me too long to send it back, not to mention I actually have 2 good cables in use that I won't be removing.
