Comments: The Inch worm breaks very easily. I've gone threw 2 in the past week. The Gamma Shockbuster is that I have now and it works great.

Comments: The Forten Worm reduces a LOT of vibration. My racquet even sounds more solid when I contact the ball. To comment on prior feedback about breakage, I've found that if you don't weave this dampener across ALL the strings (and in effect not stretching it too far) it lasts much longer. Without a doubt it’s worth a try.

Comments: It’s ok, for awhile. These dampeners are awesome when they still work, but they snap within 2 weeks. Go with the Gamma Shockbusters.
