Review on E-Z Ink (TM) Compatible Drum Unit Replacement for Brother DR420 DR 420 High Yield: Ideal for HL-2270DW HL-2280DW HL-2230 HL-2240 HL-2240D MFC-7860DW MFC-7360N DCP-7065DN - (1 Drum Unit) by Brandon Skeet

I've only had this item for two weeks. too early to give a full rating (hence 4 stars) assumes you can print approx. From 10 to 12,000 pages, depending on certain conditions. I haven't printed but about 125 pages (so far so good though). I hardly see any difference in printing between the EZ ink drum and the original Brother drum that I replaced. if it continues to work and last as long as the original printer drum (12,000 full pages, maybe more) I'll be very happy. It was delivered on time, well packaged and easy to assemble. much positive. Let's hope they hold up.
