Long I was skeptical as to whether the quality is right at this price and waited with the rating. Until long but everything is fine. Mostly I have yet to make the second round from the set in use and could no negative findings: - The colors do not differ with my applications from the Orignalfarbe. - The light resistance so far as it is to fürhen back to the corresponding ink, yet the original ink. - The recognition of the cartridges carried out in the printer easily. - The fit is very good. - The handling is different from the original cartridge auber well. - The delivery was very quick in sufficient packaging. If nothing happens, I'll buy these cartridges.
