I have been using them the last couple years. Haven't had any problems with mine. I shoot quite a bit in the summer. Don't really remember having to put new ones on to often.I just check them once in a while, just pull on the side a little, pretty easy to check for wear. Mine have seem to hold up pretty good w/ a #62 draw weight. I just go a head and replace them when the archery season starts. Don't shoot as much then, just a few shots before I head out.
