Well worth the price
It works for PS4 as stated in the box.
However this controller does not have: LED light, motion control and mic/audio jack (whatever you call it). There's a little touchpad bar but I'm not sure how it works.
The R2 and L2 trigger is somehow a button and a trigger. You can confirm this by plugging in the controller to the PC, and under the device property it will show the trigger button does register different input when you press the button harder.
The controller wire is really long. 2 or 3 meters long. You can use it on your PC Steam games and somehow it will register as a steam controller. For non Steam game, you can use x360ce.
The controller is small - it is made for kids. It might feel awkward to use initially. This gamepad is perfect for platformer games.
