Have the printer for about 3 months now and the first time the cartridge was empty before 1 Week ... I have to say: Super print quality, almost no difference to the originals cartridges, were recognized directly from the printer (there was something jittery, obs works) had there ever really grab in the S ****** last MP550, this time no problems at all. The color report at and after pressure very pushy, but flies to the drying of the ink.
