I bought the printer cartridges as an alternative to the very expensive original HP cartridges. The first impression was very good. Even the expression was comparable to the OE cartridges. Why only one star? After a short joy of cartridges came the bitter awakening. The printer reported "no round in the trade". After laborious manual cleaning I could print again 3 pages before the message "Incorrect or missing print cartridge" came. This mistake I could not fix with laborious cleaning. I then re-bought a set OE cartridges and can now return to normal print without error. Conclusion: The purchase has also cost some money except me nervous, so never again.
