Wilson Tennis Racket Vibration Stopper Shock Trap 1 Piece Shift DAMPENER 2 Pieces

Admittedly I find with these it's hard to tell how effective they are. I do think that it stays in place quite well. It's a little effort to put in at first but then that makes it harder to come off which is what you want. I have seen standard traps fly off other rackets in the middle of play.It will partially come off from time to time but it's easy enough to put back as most of it will already be in place. When that last happened I could hear the difference in the strings, I actually thought a string was gone but it sounded fine when it was back in so I think it's doing more than I thought.

Best damper available in my opinion. Covers many strings and is easy to fit.

Tricky to get on but works well.. better in fact than any other dampener I've had in the past. Because of the way it fits to the strings it can come loose at the edges if struck by a misplaced ball and if that happens it holds up play for at least 30 seconds while u try to get it back on normally hurting your fingers a little. It's come off twice for me in about 20 hours of play so not too bad really. All in all the positives out way the negatives and if I lost it tomorrow if buy another one without thinking. And it looks good too!

All too often, the usual little round/square dampeners go flying across the court. This one though largely stays put and is my favourite. Yes, it's harder to insert...but its it stays in longer too. I always try and keep a spare to hand.

I’m a beginner to intermediate level player. Sometimes I play well, sometimes nothing works and I want to hit myself in the head with my racket. Either way this dampener would stay where’s its supposed to be. Very happy with it.

Great at taking away unwanted vibrations, which is exactly why i bought it. Much better than the smaller dampeners, it's both more effective and doesn't fall out.

Is good enough for what I need

I love this dampener: it is very hard to get it in, but when it's on, it will stay on!
