I was a little suspicious but I gave it a shot. Time delivery a bit long but a little ahead of schedule. The cartridges are packed. Compared to the original kit, the photo black is provided. Problem no installation, the printer sends a few messages that intimidation must not linger. And it works! Remains to be seen how many pages will be printed. A priori the print quality is satisfactory. Given the huge price difference with HP cartridges, I think the experience is worth it.
