Despite a poor packing at first glance, one is quickly satisfied with the quality of these cartridges.
Both by its ease to set up by its print quality.
As for me, I only text prints on paper 80gr (A4 plain paper), so that's enough.
The colors are clean, crisp and consistent with my expectations. No paper test pictures.
Regarding longevity and the number of copies, I can not currently give you this information.
Anyway, I remember that 10 I have the same service if I pay 30 at a computer vendor.
See for yourself, here !!
Good luck.
