Review on ⚫️ E-Z Ink (TM) Compatible Toner Cartridge Replacement for Brother TN450 TN420 TN-450 TN-420 for HL-2270DW HL-2280DW HL-2230 HL-2240, MFC-7360N, MFC-7860DW, DCP-7065DN, Intellifax 2840 2940 - 1 Black by Robert Correa

I'm trying to keep a few cartridges handy. I haven't used my last purchase yet. Of the two previous cartridges, one was excellent and the second was practically useless. The defective cartridge had a clearly visible chip that was broken off, causing a solid black line to appear down the center of the printed page. When I got the cartridges up and running it had been too long to ask for a refund or replacement. I'm just thinking what it costs if one out of three or four is defective.
