"Best dampeners on the market; easy to insert into closed string pattern frames and looks great."
"Helps with vibration dampening. Does seem to pop out quite often during play though."
"Great dampener! the hollow center makes me think that this has the most minimal effect, which i'm not sure is true or not, but the placebo effect works on me."
"Well, I never used one before and didn’t buy this one either??"
"I have been using these for years. Just enough dampness and not overkill. I like the donut shape versus those with no hole. Just my preference, but these have been true for a long time."
"Overall satisfied with this dampner. Cheap and light. Looks good."
"I bought this Pete Sampras vibration dampener white and they work great on my racquet! Also, they look very professional because I say so. BUY IT NOW and you will look professional as well. Buy it! Buy it! Buy it! x infinity. :"
"Just great solid classic dampeners -"
"Great color which I love, goes great with black strings! Sampras dampeners are the best! Easy to put on, flexible and not stiff"
"I had never used this brand of dampener before but was very happy with it. Unlike some others, it stays in place, lessens vibration, and is hardly noticeable. Good quality and great price."
