RE: STS PROBLEMS
My STS made a huge difference as well, Ive had no problems w/ the stopper coming off. The set screw came loose once cause i forgot to tighten it really good. But other than that, Its a great product. My bow is 50-60% quiter, absolute 0 vibration/hand shock, Not to mention it gave me about 4 fps on my arrow speed. Sorry you had a bad apple, im sure STS will take care of you. I would recommend the STS to anyone.
