Early model has “shark gills” around the ball that lights up.

Review of “Logitech Wireless Trackball M570” by jared0x90.

The “Logitech Trackman Wheel Optical” was the most popular. The great thing is that it is well designed for right hand, and has a scroll wheel. However, the ball is small, and for the thumb.

The newer model is Logitech M570.
