Review on Silicone Conductive Rubber Pads for Sony Playstation 4 PS4 Controller: Ambertown 1 Set - Repair/Replace Dualshock 4 Buttons by Alonzo Wilkins

You may only need a few pieces from this set, but it has everything you need. Your shoulder buttons, you may not need new pads at all. On earlier models of the PS4 controller, the backs of the buttons may cut into the silicone pads and cut a small slit, causing the buttons to lose sensitivity. Convince yourself before you buy! You may still need this kit, but your buttons will continue to cause the same crashes if you don't fix this problem.
