Product Details:

Just to give you a small refresher course, the DUALSHOCK 3 wireless controller includes pressure sensors that rumble with each action. SIXAXIS technology is also included, so you can still use motion control, and the controller features Bluetooth technology for wireless gameplay. You can pick it up at any of the major retailers and at a cost $54.99 MSRP.
