I have had two cartridges in a row that either malfunctioned with the chip or was leaking when I got it. I rely on this expensive ink for my business and have been beyond frustrated.
Cyan Cartridge identified as "Foreign" and will not load. Needs to be returned and replaced. Fortunately for me I had more than one, because plotter would not operate until a working cartridge was installed and my business would have been dead-in-the-water. You can't make this crap up! Whose in charge over there, anyway?
[This review was collected as part of a promotion.] I ordered the ink cartridges for my company's HP plotter and the toner lasts pretty long! We frequently print large maps and the data doesn't smudge and it's readable.
