This is the second time I buy these cartridges. Except for two cartridges, where it took me a bit to find the position that it should be recognized, printing is perfect. For me, and I am not "short-sighted" and not require super, the result is comparable to the original cartridges (I speak of photo prints) for a price divided by 10. (170 minimum for 15 original cartridge ) I know other people buying compatible cartridges of another type but the same supplier: no print quality problem either. On the number of printed pages, I have no facts to say that these cartridges last as long, but I think it must be the case: the difference must be very sensitive. It's still very interesting, even if one or two cartridges were not recognized.
