The Logitech Cordless Action controller is Logitech's second attempt at a wireless controller for the Playstation 2 console. This controller is a fantastic design, and I prefer it to the official Dual Shock 2, a feat when considering the high quality of Sony's controllers.
The controller has fantastic battery life, and will last months without needing a battery change. You can choose to enable or disable vibration, and the battery is still good even with the strong vibration.
The controller also has a slightly different design than the official Dual Shock. The controller has quite a bit of heft thanks to the batteries and vibration motors. The face buttons are positioned on an angled plane, as opposed to the first-party controller. I would recommend this controller as a standard purchase to any PS2 owner, relegating the Dual Shock to the secondary role.
