The RSL Sonic 828 badminton racket is designed for beginner to intermediate players. This racket is built with Poly-Matrix Carbon, a new technology to combine different layers of Structural Carbon and High Modulus Carbon together. It results in 19% more strength to our high tension frame. This means better power transfer and more accuracy during impact. It is also built with anti-twist technology, a new Super High Modulus Multi-Layered Graphite, and the right amount of ingredient combination on RSL shaft creates Super Durability, Flex Power and Stop Shaft Twisting. This helps to increase racket's durability and overall improves execution with Power and more Control. Box designed frame at top and bottom gives you the power to smash while the sides of frame reduces air resistance and promotes quick swing. Both features join forces to create a powerful design in racket frame technology. With its wrinkle free technology, less material is used to achieve Super Strength, thus creating a well balanced racket with strong material in shaft and handle. This racket is very well balanced and awesome to play with, and with the price over performance, it gives you the best value for money.
