I can't say anything about the quality of the ink yet as this is the first time I have installed these cartridges. At the same time, ink from new cartridges fell into my hands (photo attached). I've never had this before. When I pulled the piece of orange plastic off the new cartridge, the ink literally sloshed all over me - when that was done the cartridge stopped leaking. Also, it was very difficult to find where to peel off a strip of paper after opening the package with cartridges, but after comparing them with those I took out, I understood what to do and set about it. It was very difficult to clean and didn't come off clean. In the end my printer is happy and the printed test pages look good so I'm hoping that's the only thing I'll be dissatisfied with these cartridges as the rest of the reviews are so good and the price is right.
