SPORTIC 8 pcs Tennis Racket Dampener, Racket Shock Absorber to Reduce Vibration, Tennis Racquet Vibration Dampener, Racquet Accessories for Tennis Player Sports Favor-4 Colors

These dampeners work great. No more vibration on the strings or my hand. I can hear the sweet spot 'pop' more clearly on every hit. They are easy to install and stay on the racket. I stretched my dampener across all 12 main strings. Great price for players with multiple rackets. Very happy.

Works at well as the Gamma dampener I’ve been using for significantly less $.

For the price these are hard to beat. They work well but they may not last as long as other more expensive dampeners. Still worth it though because of the price. You can easily just replace a broken one with another if necessary.

Didn’t love these. Popped off more than the round ones you put between 2 strings. I used 2 and they did absorb shock

Work great, awesome value, easy to put on racquet, & stay in place. Would buy again.

These provide great dampening but I get the sense that the ones I received were old stock since the hooks on a couple of them broke off while they were new.

Gives good string tensions.

Great product. works well. Good price!

The plastic hooks are easy to break after couple of weeks
