My printer (Canon MP-180) has accepted these cartridges without any problems and the printing result is indistinguishable from the original cartridges from Canon. Without masking, resetting the printer driver or other technical tricks I could immediately go on to change the cartridges to print, as if nothing had happened.
Only the ink level indicator may not be the new cartridge; I find myself constantly with the message "Caution: Low level" confronted; Affect the pressure or the operation of the printer takes the not - so five stars.
