I was replacing the rubbery string dampeners that you weave in between the strings because the hooks kept popping off my strings every other shot and I spent half my time reconnecting my dampener. These fit very snug on the strings and did not come off my racquet once even with some mishits that would normally pop a dampener off.

Sometimes, people just deserve a middle finger in the face. Wanna let your opponent know how you feel, but can't risk another code violation? Now you have a way to deliver without incurring a penalty! A subtle racquet flick on a changeover becomes the most satisfying gesture thanks to these dampeners!
In all seriousness, these things are pretty good. Dampeners tend to go flying every time I step on court, (looking at you, Wilson) but these ones fit well and after a few hours of hitting I've had no problems. If you're in the market for dampeners and want something entertaining, these are for you. Also, props to the seller for contacting me personally to make sure everything went well with the delivery.

I love these! I am the envy of my tennis team mates.! They do provide anti vibration the way they should be doing it so not only are a fun way to decorate your strings it also provides the function they are supposed to be doing. I highly reccomend them!

Picked these up and played a big match with them yesterday. Came out firing on all cylinders and lost our first set. I noticed then that it wasnt me that was the problem. It had to be my partner. Obviously with my new found FU approach to the game there was no way to blame a 2-6 loss on myself.
Luckily my package came with two middle finger tennis vibration dampeners.
I loaned, because I dont give stuff out for free, the other dampener to my partner.
The beauty of these dirty dampners was not only was a giving a middle finger to my opponents but also to my crappy partner. Now with both of us able to shed some hatred on each other we were able to dominate the competition. Won the second set 6-4 and tiebreaker 10-7.
I think I even saw one of those losers had a peace sign dampener. LOL, are you kidding me, Give peace a chance on some other court. I am here to straight DOMINATE. Which these dampeners helped me achieve.

would give six stars, 5 on one hand and one on the other, you know which one. Thanks Dirty Dampeners.

Delivery was on time, and the product was exactly as displayed on Amazon. They fit on my racket, and have not had any problems with them. I really enjoy the middle finger dampeners. I get to tell all my opponents that they are "# 1" in my book! HA!
