So I decided to take a chance and buy regular HP cartridges. For at least 20 years I've mostly just stuck with the brand name. I thought generics were a scam when it came to ink or that a brand name should be of the highest quality. Uniwork proved me sooooo wrong. I've replaced two cartridges so far and they work great - no problems. The best part is the money I save. I get twice the ink (actually a bit more since you get three XL blacks) for a lot less than a box of HP ink! For your health.
