Review on E-Z Ink (TM) Compatible Toner Cartridge Replacement for Brother TN450 TN420 TN-450 TN-420 - Compatible with HL-2270DW HL-2280DW HL-2230 HL-2240 MFC-7360N MFC-7860DW DCP-7065DN Intellifax 2840 2940 (4 Black) by Chris Crawford

I started using the first of 4 cartridges. I am very satisfied with the print quality. It's at least as good as the OEM stuff, which costs more per cartridge. Whether each cartridge will last as long as the TN-450 remains to be seen, but I'm not overly concerned about that. If it only lasts as long as the starter or TN-420 then it's still very valuable to me considering it's a home printer that I only print once a week at most. The only reason I think it doesn't last as long is because the cartridge was a lot lighter than even the used TN-450 it replaced, although I thought it had more to do with the design of the parts . While I think about it, I'll update if anything goes wrong or if the toner life is more limited than expected.
