"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".
"The feel you get from the WinSock is incredible. After using it I feel like my whole game is flowing in a most natural and efficient way. The high level juniors I coach love it too. "I can't recommend the WinSock highly enough as a must have for any coaches toolbox. It flat out produces results."
"Big Wins With The Winsock"
"The Winsock is very useful in helping students to execute a full finish on groundstrokes, to let the racket turn them in recovery to the center, and to develop upper body strength".
"It should be in every player's tennis bag".
"I tried the WinSock and I really like it. I think it is especially useful to develop the capacity of acceleration in the motion to strike in groudstrokes and the ability to control the racket in volleys."
"It is very good because it can give real feelings of the game. The shot control is possible also with the heavy racquet and this permits to transfer the ability when I return to normal condition."
" 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".
"Really like the ProTrainer WinSock...its a great warm up tool. I would recommend it to anyone".
"I'm happy to report that I'm really enjoying the WinSock. I've used it in warm-up 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".
