Uxcell Tennis Vibration Dampeners, 4 Pack Shock Absorber Racket String Damping, Black

The tennis dampener can effectively reduce the vibration generated by the ball hitting the string to increase comfort. With this shock absorber, you can obviously feel the reduction of the vibration and the change of the residual sound at the moment of hitting.

Advantage
It works really well at dampening the vibrations and you never have to worry about it falling off. Reduce the hurt to the elbow joint caused by vibration, and improve sports fun. The lower resonance allows for better control when swinging through the ball.

Instruction
It is easy to install and helps with vibration when hitting the tennis ball with minimal detachment issues and zero blowouts.

NOTE: Instead of tying it into a knot, just thread it into the strings closest to the throat and secure the end between two strings at the crossing.
