Sony PS2 Controller PlayStation 2 Dual Sock – Black

The layout of PlayStation 2’s Dual Shock 2 controller is nearly identical to that of the PlayStation’s Dual Shock controller, which is good news for most gamers.
The main new feature is that, when the buttons are pushed, the controller can register how much pressure is being exerted. This adds a completely new dimension to sports, racing, fighting, and more games. Aside from the Start and Select buttons, all of the functions are analog for greater control, a wider variety of operations, and a more compelling interactive experience. 
Two convex analog thumb pads and two force-feedback solenoid rumblers round out the features. This controller is also compatible with all software that supports the Dual Shock controller.
