I've only had this ink for a few weeks but so far I'm very happy with the quality and price. One thing I would like to point out is that the small clear plastic (or cellophane) cover of the ink port on the cartridge is quite thick. This cellophane coating is supposed to puncture automatically when the cartridge is inserted into the printer, but after several attempts to force the cartridge into the printer, the cartridge does not "seat" properly. I thought the cartridge might actually be the wrong size. But then I grabbed a thumbtack and poked through the cellophane and the cartridge clicked into place. Poke a hole in this cellophane if the cartridge is not seated properly.
