Product Reviews: “Bought this racket as back up to my 03 red but play with this one all the time. Has a much more solid feel and inspires confidence on the control and direction of the shot. Seems hard to mis-hit with this racket and has really helped increase my racket head speed and attack shots that I would have before blocked back. The extra racket head speed has really helped in gaining those crosscourt angles. I think that this is a racket that you can continue to use as your game develops without having to change up. Also a very comfortable racket that still provides feel for the ball. Highly recommended.” - Gary, London, England
