    Rated 4.3 out of 5�by 61 reviewers.
    Rated 1 out of 5�by Worst purchase ever The first HP 45 ink cartridge leaked and ink was everywhere. a real mess to clean up. I hesitated to put the second one in but it appears to be holding. I threw the carcass in the trash where it belongs. November 2, 2015
    Rated 5 out of 5�by Nice Rich Black Print The HP 45 Black Ink Cartridge gives my document that high quality print look regardless of the type of paper I use. October 5, 2015
    Rated 5 out of 5�by Ink Cartridge This is a spare cartridge for my old HP printer that still works after being used for 10 years. I have always bought new... When printing it never pays to be cheap. October 5, 2015
    Rated 3 out of 5�by Good Purchase It's the ink cartridge that goes with the printer I currently have at work. It is good quality ink, it doesn't smear and dries quickly. October 5, 2015
