I can not connect the positive reviews. The image of both black cartridges was very uneven, a pressure in the economy mode is not possible. Calibrating and cleaning the printheads did not improve, so that actually had to be always printed with ink, in order to achieve an adequate print image. Thus, the cartridges were then relatively quickly. In the colorful yellow color cartridge chamber did not work; the weight compared to another new cartridge was suggested that the board was simply not filled during reprocessing. Thus, this cartridge was completely unusable. The bottom line is therefore a program of three rounds, none of which was free from significant defects. Maybe I've also had only maximum pitch, but what is at best a poor consolation for me.
