The only unusual was that our Magenta cartridge significantly darker acts as the me known magenta cartridges; I have, however, not that this influenced in the previous color copies the impression the color values in the print key.
All in all, they seem to me to be a real alternative to the original cartridge when shopping and at still acceptable pricing. Other Refills are certainly cheaper, but as expected you have then also with quality shortcomings (up to the colorful bleeding in the printer). I think we will come back to it next time.
