Easy to install: tie the shock absorber to your racquet string to secure it and prevent slipping during play. Long shock-absorbing knot: the extended knot design increases contact area and maintains a firm hold, improving durability and tensile strength for long-term use. Reduces vibration and fatigue: absorbs impact from ball strikes to lower hand vibration, reduce hand fatigue, and help you stay comfortable longer. Better control and consistency: by damping unwanted string vibration, it helps stabilize your shots and can improve striking accuracy and feel. Designed for on-court use: suitable for matches, training sessions, and recreational play where vibration reduction and consistent contact are important. Key attributes Function: vibration dampening and shock absorption to protect the hand and stabilize hits. Compatibility: attaches directly to the racquet string; intended for use with tennis racquets. Durability and performance: long knot and strong tensile strength support reliable, long-term performance under regular play. Typical applications Match play: reduce distracting string vibrations so you can focus on shot placement and timing. Training sessions: protect your arm and maintain comfort during high-volume hitting or practice drills. Recreational games: improve feel and control during casual play while minimizing hand fatigue. How to use Tie the absorber to a main or cross string where you prefer the feel; the knot keeps it from sliding and maintains position during strokes.
