TRAXSYS' Roller II line are sturdy three button switch adaptable pointing devices. They come in either a large 2.5" trackball or a 3" joystick. They have separate buttons for left click, right click and drag lock with color corresponding switch ports on the back of the units. A flashing light indicates the drag button has been activated. The Roller II products include a keyguard to help users isolate on the buttons. INCLUDED with the Joystick are the two alternative handles to accommodate different input needs: T-Bar AND Soft Sponge Ball.
