Review on 🖨️ Uniwork Compatible Toner Cartridge Replacement for Brother TN850 TN 850 TN-850 TN820 - Compatible with Laserjet HL-L6200DW HL-L6200DWT MFC-L5900DW MFC-L5700DW MFC-L6800DW HL-L5200DW Printers - Tray 2 - High Yield - Black by Jason Flores

Full five stars. I've been using this toner for years so it's easy to give a five star review even though the manufacturer provided me with a cartridge. I print addresses onto printed flyers by the thousands at a time and typically get between 2000 and 2500 per cartridge. I've attached a video so you can see how sharp and crisp the print is. I have had this printer for many years and have never had any problems with this toner. It is also well packaged and arrives quickly. In fact, this set of two cartridges arrived the next day after ordering.
