Apple Optical Pro Mouse - White. Model M5769. Used, tested working.
The Apple Mouse has no rollers or tracking mechanisms to wear out
or clog, and no mouse balls to fish out and clean. Besides all
that, there's no distinguishable mouse button. Instead, the
entire Apple Mouse is in effect a super-sensitive button - the body
pivots up and down to actuate the click mechanism. The elliptical
shape equally accommodates right and left-handed users, and its
glass-smooth surface makes it a joy to use.
The Apple Mouse uniquely combines simplicity, elegance and
precision to deliver a superior mouse experience.Its ideal when
working with applications like Photoshop or Illustrator which
require precision cursor movement. Its equally adept on most any
surface and maintains accuracy even during rapid movement.
