I once fitted a slinky glide on one of my other bikes, it lasted maybe a month. It was supplied with a plastic ferrule (the sleeve that fits inside the hole in the lever) and it rapidly became chewed up. The original had a metal sleeve and the sleeve was still as new, so I fitted the old sleeve onto the new cable. Basically, the plastic sleeve wasn't fit for purpose.
