Review on High-Quality Aztech Compatible Toner Cartridges for Brother Printer TN850 TN-850 TN 850 TN820 TN-820 - Black, 4-Pack by Kyle Rodman

I have been using this printer ink in my office for a few weeks. We print around 150-200 pages a day in daylight and these inks are state of the art. I don't see any unnecessary ink streaks or loss of quality compared to genuine Brother inks. I first bought it for 4 packs because of the amazing price and just wanted to try it. Again, since this was for my company, I needed to make sure the printouts met the company's requirements and that the first cartridge worked well. If I see problems, you will be informed in future updates. For now I am happy with the cartridge and would recommend it to all of you.
