The Revolution series come with 4 x programmable back button - We have not included a Hair Trigger Mod , as featured on the Tournament edition , so as to preserve the Haptic Feedback on the Dualsense controllers ( When you install a Hair Trigger Mod , the Haptic Feedback is disabled ) 

The problem with aftermarket controllers , is that the quality is never the same as an Sony original controller . There are also no spares for them . This scuff-like controller is an is an original , new Dualsense controller - We have added a state the art , programbble 4 x back-button kit with a redesigned back shell with integrated rubber grips . 

This Mod Controller gives you a competitive edge in Online Gaming and Tournaments, and is totally legal.

You can remap 15 buttons to the 4 additional buttons located on the back of the controller - It’s a huge advantage for you because you don’t need to move off the sticks and triggers to access other buttons during fast FPS or shooter games.

On-the-fly Buttons Remapping:  Just press and hold the Set button on the back for 3 seconds to enter the button setting mode.You can activate the remap mode during the game and assign a maximum of 15 buttons (X, O, Triangle, Square, Up, Down, Left, Right, L1, L2, R1, R2, L3, R3 ) to the back buttons.
