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

I installed this in our Brother printer on November 28th. As of 1/7 he's still going strong. It is used primarily by two people in small businesses, although other employees sometimes come and use the printer. We set it up on our wireless network and it's easy to send a print job to it. It's still going strong. I don't have a page counter, but if it lasts 2-3 months, then we're regular customers. Normally this is our standard. Thank you for reading!
