Adesso HA-4003UB Mouse

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. primary informationinput device type:notebook mousedevice form factor: externalconnectiv ity technology: cablemovement resolution:1600 dpiinterfaces: usbdimensions&mis cellaneouswidth:3. 6 inchdepth:2 inchheight:1.5 inchcolor: blacksystem informationsystem requirementssyste m requirements / os required:windows vista/xp/2000/me/ 98seunspsc codeunspsc code: 43211708product idupc: 783750003506manuf acturer part:h
