Review on Brother Genuine TN850 2-Pack High Yield Black Toner Cartridge - Approx. 8,000 Pages per Cartridge by Bob Novitsky

I know this toner is expensive BUT it lasts forever. Other universal toner buyers use twice as many cartridges. It is worth buying real toner for brother! When your printer brother tells you it's time to replace him. NOT! Watch a YouTube video on how to reset the device and I promise the toner will last a long time afterwards. I don't change mine until I see the toner fading.
