I had a similar experience when while at The Potter County bow festival here in PA I managed to break 2 of the fiber optics on my pins I don' t quite know how I did it but 2 of them were broke. So I emailed Copper John just to ask them where I could get replacement fibers and they emailed me back saying that they would send me replacement fibers at no charge. Within a few days I recieved the fibers and my Copper John Dead Nuts Pro was as good as new. I know with service like that they made a lifelong custmer out of me.
