Very easy to install. Really convenient to use. I have a few different KontrolFreek mini joysticks and while they're not my favorite, I still enjoy using them depending on what game I'm playing. KontrolFreek branded sticks are slightly more expensive, but compared to cheaper sticks, they are far superior in performance. Sometimes I'm really into gaming and tend to push the sticks too hard and with the cheaper sticks they come. turned off while I'm playing, so I have to stop the game and turn them back on. But with KontrolFreek brand joysticks I never had such a problem. The way they grip the joystick keeps them firmly in place no matter how hard I push them. The only problem I had was that they stick too much so after switching between different types (low height, medium height depending on what I'm playing) the rubber on the original PS4 controller joystick starts to tear and dissolves. It's not a big problem yet, but I know I'll have to find a way to fix it at some point.
