Review on 🔄 E-Z Ink (TM) High Yield Drum Unit Replacement for Brother DR520 DR620 - Compatible with DCP-8065DN, DCP-8060, HL-5240, HL-5250DN, HL-5340D, HL-5370DW, MFC-8890DW, MFC-8460N - 1 Drum Unit, 1 Pack by Matthew Maggot

I was one of almost 1/3 of the reviewers who found this drum useless and unusable. Such imperfect quality control should be enough of a warning, but I've learned my lesson. The drum created halos and ink spots on the paper, and no adjustment of the printer/copier settings helped. I wasted dozens of pages to give him a chance to clear up but to no avail.
