Review on GPC Image Compatible Toner Cartridge Replacement for Brother TN-450 TN450 TN420 - High-quality Ink for HL-2270DW HL-2280DW MFC-7360N MFC-7360N MFC-7860DW DCP-7065DN IntelliFax 2840 2940 Printer Tray (4 Black) by Jason Tinnen

The new toner has been used fairly consistently, around 25 pages a day since I installed it a week ago. So far the quality has been excellent. The price was phenomenal, around $35 for four toner changes! Essentially, this is the price of replacing a brand name. While I didn't need the toner replacement guide, it's nice that it came and was well written. With this printer model, and I believe others as well, there are sometimes special ways to install toner so the printer knows you did it and resets the toner low message. Very happy at the moment. My only concern is whether the quality will hold up for the next few weeks, hence the only four stars I've given. If the quality holds up I'll change it to five, and if not I'll change it to three!
