Features:
The cursor control is provided with optical technology. It has sliding roller bar and provides smooth spinning. It reduces shoulder injuries and elbow injuries by keeping hands in optimal work zone. For repetitive tasks such as double clicking and drag lock, programmable buttons are provided.
The longer roller bar gives ample room to have both hands (all 8-10 fingers) on the roller bar at once. This ensures greater flexibility and variation.
The roller bar is closer, as is cursor movement, regardless of where your hands are on the keyboard. This is a big advantage if you frequently use the numerical part of the keyboard.
Last but not least, it is now possible to manoeuvre about on the ever-larger screens currently used in many office environments using a minimum of movement.
