Review on 🖨️ E-Z Ink (TM) Replacement Toner Cartridge Set for Brother HL-L8260CDW HL-L8360CDW MFC-L8610CDW MFC-L8900CDW Printers - TN433 TN431 Compatible - 1 Black, 1 Cyan, 1 Magenta, 1 Yellow (4 Pack) by Mike Quade

The toner quality is excellent. We had no problems with color cartridges. However, the black cartridge basically squirts black toner everywhere. This results in blotchy prints and tons of black ink powder all over the inside of the printer. I've tried everything to get it working properly. I was delighted to find cartridges at this price that have received such positive feedback. Our company is quite small and to save costs we print most of the products ourselves, but the results are not very good so far, solid black spots.
