We use this cartridge in a Brother MFC-J5910DW. They fit well and provide a good to very good printing result on "normal" paper. On glossy photo paper, the ink blurred even after long drying considerably more than the expensive original ink. We had to go back for certain printing tasks to the original ink. For our everyday prints on "open-cell" paper these cartridges save us some cash.
We find this limitation regarding. The print quality on glossy paper important and therefore awarded "only" four stars.
