Product Reviews: “I upgraded from the O3 Silver to the Speedport version, and although the improvement is marginal, it is worth it because it increases the racquet speed at the point of contact, generating more power with a shorter swing. I play with a short and compact swing and this racquet allows me to play all over the court and keep up the pace and pop no matter where I am hitting from. At net it is great for me, as I also have a compact volley motion. If your swing fits the short and fast category, the Speedport Silver is for you. A great choice for club doubles players.” - Enrique, Dubai, UAE
