If you are a tennis buff (like me), you would understand to be on top of your game you need to have a tennis racket wherein you play your best. Although not a Roger Federer-like or a Serena Williams-like when playing, at least one has to be competitive. This can be achieved when you are equipped with a tennis racket that suit you best.

The Wilson K Factor K4 is one of the newest tennis rackets launched by Wilson, the world’s leading manufacturer of tennis rackets. The K series rackets were designed using the Karophite Black structure giving them a stable feel. K4 is especially designed for players looking for more pace and spin in their shots. It has the ultimate combination of power, stability and control. It has a unique frame engineering to provide increase feel of strength and stability at the same time giving it a bigger sweet spot in a mid plus head size racket. For top spinners, this racket is very effective in power and control, maintaining a full swing stroke in both forehand and back hand. It has certain stiffness in a wider beam that gives the player consistency in every shot. Aside from what it can do, the K4 is a good looking racket with its blue, white and black combination.

On the other hand, the disadvantage of this racket to a flat stroke player who usually doesn’t complete a full swing would result to a constant outside shot on the baseline. For players who are used to a 55-58 string tension, this racket doesn’t perform well since it works well with a high string tension of 60-63kgs. Like all good tennis rackets, the K4 is quite expensive the first time it was introduced to the market. Market price ranges from $200-$250.00 and has limited availability.

This racket was called K4 because of its [K]oraphite black structure, [K]ompact center, [K]ontour and [K]ontrol. All in all, despite a few disadvantages on the price and availability, K4 is a racket worth having if you are a player who feels the need to improve the stability and power to your game.
