Have 2 Brother printers fit into these cartridges. A MFC-J615W and MFC-5890CN. In both there are no problems with the cartridges. The printers are now 3 and 5 years old and I use these cartridges for 3 years and over again. I print a lot of (small graphics) and can only positive things. In the mode "Normal (faster)" you can read everything without going well and at the modes "Normal" and "Fine" also runs nothing. By 5890 I print DWG drawings, A1 and A0 are the original A2 to A3. You can see everything very well. The Aussnutzung contents is ok when the printer indicates that you should replace the cartridges, you can still safely 100 - print 150 DIN A4 pages described. In terms of price / performance, the cartridges are perfect. I do not know how many copies I really do, but there are a whole lot. I need about every 1.5 years, a new set for both printers. Did she just ordered for the third time and all is well!
