And, my return window closed 2 weeks ago, so it seems I can't do anything about it, besides write a lousy review.

SorryI gave you a bad review

I also read reviews complaining about how long the cartridges last, but I have never bought an hp cartridge that prints the 480 pages they say it will

I limited my review to four stars only because I have yet to use the ink.

See my past reviews, always the same good review (20+ words).

BEWARE!I highly recommend that you do not join HP instant ink program

These came in so fast I, was so surprised
