    Rated 4.1 out of 5�by 74 reviewers.
    Rated 2 out of 5�by expensive ink since 2006 I have an hp printer that I bought since year 2006 and I still use them at present.I always think that why inks are so expensive when the cartridge is too small and the ink only lasts for a short period of time. I would like to receive big discounts when bringing back the empty cartridge to participating retail outlets.It is recyclable container and costs less than to manufacture new ones. October 5, 2015
    Rated 4 out of 5�by HP toner cartridges Have always used these cartridges and have been very happy with them. October 5, 2015
    Rated 3 out of 5�by printer cartridge Was thankful to get a cartridge to replace the one I used up. The customer service person was very helpful. September 14, 2015
    Rated 2 out of 5�by Too Expensive This black ink cartridge is too expensive !!! Also I purchased the incorrect tricolor cartridge because it was not listed correctly and now I have to take it out of my printer and return it to the store. September 8, 2015
