Up to four lights show pointer speeds from slow to fast: slow speed or low DPI for precision work such as photo editing or drawing; fast speed or high DPI for quickly moving across the screen for general tasks.
A laser sensor ensures reliable tracking on most surfaces.
The receiver may be stored behind a magnetic battery cover.
