First, the buttons and joysticks on the PS4 controller that came with my 1st gen PS4 work fine. Having recently opened up my PS3 controllers, I decided to order replacement buttons and fit them into my PS4 controller as one of the joysticks had a rubber grip completely ripped off. This requires a lot of know-how. to open the controller where the buttons and joysticks are so you can replace them. I removed the battery (not wanting to short anything) and the ribbon cables attached to the touchpad and turned off the LED so I could work on what I replaced. To be honest, the controller looks way better with a pink color and a black controller as the "background". I am definitely planning to order another kit for my other PS4 controller in a different color.
