I've got one on my Victory,and I love it too!I compared it against a vibracheck Icon,a solid metal PSE with a stabilizer enhancer,and a golden key tranquilizer.S-coil was the best.Suprisingly the solid metal PSE w/the stabilizer enhancer was next best,then the tranquilizer,and lastly the Icon.Like everyone else is sayin for $15 you can't beat it!
