Thank you for viewing! I have a lot in stock, so bulk sales are also okay! New, unused, and unopened. Immediate purchase is welcome. The Reactive Paddle Replacement Kit is the latest paddle specifically for the Scuf Infinity 4PS PRO. It includes a total of 4 pieces: short 51mm L/R and long 55mm L/R. You can customize your Scuf Infinity 4PS PRO to your own liking, depending on the size of your hand and how you hold it. The Reactive Paddles feature a gently inward-curved design, bringing the buttons closer to the handle than traditional Scuf paddles. It's designed to allow you to press the buttons with smaller movements. This replacement kit is also recommended for those with shorter fingers. Compatible only with the SCUF Infinity 4PS PRO controller. Can be used by replacing the standard paddles.
