Review on Compatible Toner Cartridge Replacement for Brother TN660 TN630 - GO-TO-BY (2 Pack, Black) - Works with HL-L2380DW HL-L2320D HL-L2300D HL-L2340DW MFC-L2740DW DCP-L2540DW Printer by Bob Candfield

I bought this as I usually buy a new factory toner cartridge and decided to try it. What a waste of time and money. I believe it was a 1200 page toner cartridge, well I received a 100 page 2 sided print and it ran out of toner ok insert cartridge 2 after inserting the cartridge it still says, that toner is needed, ok, learned my lesson, sent back 2 defective cartridges and went to staples got a new factory cartridge, now the print is fine. So in my case it was quite a bummer, your experience may be different.
