These triggers look great and fit the controller snugly, but the plastic on the back of the trigger is too bulging and squeezes the trigger before it is pressed fire. I had to cut 1/8th of the plastic from the back of the trigger to make it work properly. After I scaled it down, the controller worked fine. FYI, you may need to change the trigger to make it work. It's a shame because they're so close to having an amazing replacement. I don't recommend them because I had to spend a lot of time and effort to get the triggers to work. I may add that when you press or hold the right trigger while the PS4 is loading, the controller works in the menu, but when the game loads, the controller doesn't work. This made me scratch my head until I realized that the new trigger held the inner button. As a result, you have to shave it off for the gap.
