| Marketing Information | The optical technology in computer mouse has evolved. This has replaced the traditional LED with a LASER tracking system. Now it provides a more reliable optical tracking whereas laser tracking is more accurate than LED tracking. With this evolution, it increased optical mouse performance by raising the DPI (dots per inch) count of the optical sensor. The higher the DPI count, the more sensitive the mouse becomes. While both techniques improve optical mouse performance, no company has decided to combine the two. Introducing the HA-4003UB 3 button laser mouse features both a laser tracking system and a 1600 DPI sensor.
