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 Esera Warren

I use my HL-2240D printer a lot for work, so I need a lot of toner. We've been using these EZ replacement inks for years and have NEVER had a problem with them. I love that we can order them in multi packs and that they come with reset instructions to fully extend the life of the cartridges. I also appreciate that Revain always stocks them so replacements arrive quickly.
