Was it installed by a pro shop, or did you do the install yourself? When these rests are installed correctly they usually work very well. Sometimes need a little fine tuning. Normally, adjusting the height so the center of the arrow is running right down the center of the Berger button; and setting the left-right so the center of the arrow is about .800 from the shelf is a good place to start. Once the height is set, adjust your nocking point to be about 3/16" to 1/4" above the point on the string where the arrow is square with the string.
