GlassPro Technology - Works even on glass*
Auto Power Save Mode
Long operating distance of up to 10 m
2.4 GHz Wireless Technology with USB Receiver
 
Works with at least 4 mm glass thickness. GlassPro Technology perceives the clean areas of glass as dark background with bright dots (dust) and the sensor follows the movements of these dots to understand movement of the mouse. GlassPro M2 works virtually on every surface but may not perform best on shiny clean glass as it requires minute details like dust to function.
