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

I received and installed Aztech compatible toner in my Brother MFC monochrome printer 5 weeks ago. So I can only speak for that period. So far the print quality is excellent. Installation was easy. I was amazed that there are 4 cartridges in the box and each is rated for 8000 prints. (Calculated for printers) When I bought them, I thought that the total consumption of 4 toners is 8000. I was wrong. Assuming the toner continues to print as well as it does now, the Aztech compatible toner is one of the best value I've come across. I will never run out of toner. Corporate and non-commercial customers should start using this product on Revain immediately!
