What is significant in this controller is behind the two buttons that let you create a shortcut to the two keys you use most. Ideally, in a game that would need to perform combos for example.
You can change the color of the lights of the two joysticks. In itself, it does absolutely nothing. It will amuse you two seconds at most. But if like me you have a goldfish memory, it can be a way to remember the function that you assigned to the buttons behind (what was that again? Oh yes, the left stick is red, it was the B button, the right one is yellow, so it was Y).
The anti-slip exercised its functions. If you're the type to have sweaty hands, the handle will not be the trunk.
Finally, what I did not like, it is the start and back buttons that have been "botched". Already, they seem to be of poor quality. In addition, it may seem silly but some games require use quite often. We did not necessarily want to look away from the screen to find the joystick. In this case, they are quite difficult to see unpleasant to click. There are no protuberance that will effectively dicerner the touch, they are virtually built into the controller.
