These have been used in several Dualshock4 controllers for several months. They can be installed in Dualshock4 and at first glance they are very similar to OEM. However, they are shorter and the bottom flares out further than the OEM. From what I received, some of the thumb pads weren't attached directly to the stick, making them look skewed or off-center. The resistance is practically zero, since a single application of KontrolFreeks will destroy the rubberized coating. Worst of all, they rub on the inside and you can absolutely hear it when using the controller. Not only was it annoying to hear, but the next time I serviced the controller it was completely covered in fine gunpowder inside, even in the potentiometer wheel sensors, making cleaning a real pain. Good concept, poor execution. play devil's advocate; I think if you rarely or don't play high fidelity games and don't mind annoying rubbing and sticking, this might work for you and save you the expense of replacing a controller. But if you play Call of Duty or other fast FPS games regularly, don't even waste your time.
