KontrolFreek Performance Thumbsticks are designed to provide an advantage in gameplay by increasing the controller's arc distance and maximizing agility, accuracy and grip. They snap easily on and off your controller's original thumbsticks, creating a new stick experience that will take your gaming to the next level! KontrolFreek's Rush is a unique, bold, mid-rise Performance Thumbstick with an original, raised-edge design. It cradles your thumb for exceptional speed and grip in every game you play. Rush features a softer variation of our proprietary composite material, so you get a more comfortable, personalized feel while gaming. The soft wall created by the concave design reduces slips and allows for quick reactions in all directions. It's particularly optimal for gamers who prefer to keep their thumbs centered on their thumbsticks or for those who play claw-style or with paddles. The circular pattern inside the cavity increases grip for even more control. Rotate the raised edge to customize the design to fit your gameplay needs. With 120% more surface area than stock PlayStation 4 and XBox One thumbsticks, Rush supports your thumbs for added comfort, particularly during marathon gaming sessions. The mid-rise stem snaps easily onto stock thumbsticks and adds 3.75mm of height. This increases your arc distance by 90% for added precision and sensitivity with a minimal adjustment period. The softer variation of our proprietary composite material is still extremely durable and helps wick away moisture to increase grip.
