Wilson Shock Trap Vibration Dampener

It's large enough that it never pops off.

Excellent dampener that you never have to worry about it flying off.

Best dampener there is! I have one on each of my rackets and my kids rackets. It's the only one that effectively dampens vibrations and never comes off.

works like a vibration killer! great~~~

This is the 3rd (or possible 4th) one of these that I've purchased, not because they break or wear out but because I must have one on every racquet even those I only use occasionally.
