So far so good! I’ve only been using these cartridges for a few days but so far they work perfectly. They print clearly and do not smudge, which is a must for me! I have printed about 30 pages with it so far so I will update my review in a while to let everyone know how long it lasted. The cartridges were super easy to install- no more complicated than an original HP cartridge. Just pop it into place and make sure that it is secure and you are good to go. I recommend this to anyone who does business in their home and to students (I am using mind mostly for school work). I received this product at a discounted price in exchange for an honest review.
