Only used 4 times. I've shortened the fiber optic cords to fit Canon flashes perfectly. If you want or need, you can also purchase new replacement cords for $5 each from www.radiopopper.com.
BONUS: I'm including 2 of Peter Gregg's excellent attachement bands for the receivers for free (NEW, and never used on a job. Much better method of attaching than using tape. See www.abetterbouncecard.com for details). Also, these sets are located in Canada, and I'm including shipping in North America via Xpresspost.
