Review on Improved PartEGG L1 R1 L2 R2 Trigger Button Set with Springs Replacement for Sony PS4 Pro PS4 Slim Dualshock 4 Controller JDS-030 JDM-030 CUH-1200 Console (2nd Generation) by Victor Anderson

I was a little disgusted with the installation of these triggers. Triggers L1 and R1 were not reset after being pressed. Eventually they found it too tight and chafed the small black stripe separating triggers 1 and 2. Used a thin file on the top of the trigger and something on the black stripe to scrape off some of the plastic so they wouldn't rub. Once that is achieved they work great.
