Well the first set I had on my bow where junk. after about 30 shots I started to notice the servings where separating badly on the cables. Well I got a new set from elite, and this set is much nicer. I have about 300 shots on them and the servings look just like they did the day I got them, and my peep hasen't moved. I don't know what they did but they seemed to have fixed the problem. At least with the ones I got.
