This is the wireless version of the Saitek Evo (Cyborg) product line. It is basicly the same joystick as the Evo but sports wireless 2.4G technology and a 50 hour battery life from a single alkaline battery. This joystick is fully adjustable for right or left hand use, the wrist wrest is adjustable up or down, and can be reversed. The 'trigger head' can be changed in three dimensions to suit the user. The second generation of this stick has thumb screws to allow easier adjustments.
