- What Players and Pros Are Saying About Us -

Oscar Wegner Legendary Coach of top pros like 5 time Wimbledon Champion and 6 time French Open Champion, Bjorn Borg, #1 in the world in 2000 Guga Kuerten and recognized as the teaching influence of the Williams sisters who learned to play using his instructional videos, says " The WinSock is awesome; It permits you to groove your strokes in a most natural way. You learn from your racquet, which is what I have told even accomplished tennis pros".

Daily Racquet.com says, "There is no doubt about it, this little weighted trainer helps deliver a powerful and reliable swing movement and dramatically improves swing speed and swing mechanics. The WinSock is a must for any tennis player".

"I'm happy to report that I'm really enjoying the WinSock. I've used it in warmup before my last three matches and it has really helped to loosen my arm. I feel like I'm starting faster - it doesn't take 3 or 4 games to get flowing like it used to for me".
