Howler While that is a neat pic it means absolutely nothing regarding the ability of the supressors to deaden vibration.

The Mathews supressors are way too close to the ends of the string (where they make contact with the cam and wheel) to be very effective. A vibration deadening device needs to be much farther out on the string where it would absorbe the maximim amount of vibration as quickly as possible to be as effective as possible.

Pluck a guitar string in the center of its length and then lightly touch the string 1" from both ends and then do it again but lightly touch the string 6 inches from both ends. You will instantly see a difference in the vibration deadening abilities of where your finger is placed.
