(Red, blue, green, purple) But of origin, only the purple is set in 2000 DPI. Changing color down the resolution. through the interface installed by the CD can be increased resolution for each color (more than 2000 DPI each). Moreover, original, the selected color to a programmable pulse rate or may be continuous through the interface. Quick delivery time, price gun product. Do not hesitate to visit the site Perixx.
