Good product. Does the job. No more vibration or tennis elbow. Stays in place.

Sehr empfehlenswert dieser Shockbooster von Gamma. Alle die mit Dämpfer spielen, werden dieses Teil lieben. Werde ich sicher nochmal bestellen.

I have gone through several of these dampeners over the years. They last about one tennis season as the hard plastic ends which connect the device to the string eventually breaks off the silicone. They may not be durable but they do what they are made for - dampen the tennis strings and eliminate the ping.

This dampener has a great feel when hitting and looks good, so I bought two for both of my rackets. But after playing with them for a month, they both broke in one day during my normal game. I guess the quality and design is just lacking. Enjoyed it but wouldn’t recommend.
