I took mine off because it is too loud....I have a Switchback which is very quiet to begin with...But I wanted to get rid of the slight string vibration. So I shot the STS for a week thinking it would make my bow even quieter....NOT! I played around with the gap between the string and suppressor but nothing seemed to fix the noise problem. It would make a significant pop noise when the string strikes the rubber suppressor. Without the STS all I get now is a slight string vibration noise which is noticeably quieter than with the STS.
