For the price the brother OEM cartridges work flawlessly. Between my two daughters printing and writing projects, and my wife's art projects our MFC-J475DW gets used and abused a lot, I mean they print lots of stuff!! I have yet to see an issue. It is rare to have printed as much as we have and not had any problems, but so far so good and at this point I am going to stay with the OEM brother ink. Believe me if anybody should have had a problem or issue it would have been my family, and none so far. At this point I will say that I can honestly give this product 5 stars!! I am usually the first one to complain or bring up a problem with a product, but simply put I am impressed with flawless output we have continued to get with brother ink so far.
