I have used them on four different Mathews bows with no problems as of yet. In the shop that I work at we did have a bad batch a few years back. We have sold several hundred since then and no problems yet. I don't understand why yours is so noise. I do believe you but I know it shouldn't be that way. Maybe if by chance you could post a pic of rest on you bow then we could better understand why you is making noise. Did you install it yourself or did you have someone else install it?
