These inks work very well the colors are smooth and even. And as it happens they are very easy to install and remove (to install you just pop them out of the back and into the cartridge holder you don't have to unwrap them or snap off any um snaps; to remove them you just press lightly and they pop right out). They cost an arm and a leg but that is true for all printer ink (the manufacturers practically give away the printers but make their money back on the ink).
