Review on 🖨️ RETCH Compatible TN227 TN-227 Toner Cartridge Tray 5 Pack Replacement for Brother TN227BK TN223 TN-223 – MFC-L3770CDW, MFC-L3750CDW, MFC-L3710CW, HL-L3210CW, HL-L3290CDW by Chris Hodges

Fast shipping and good packaging. No compatibility issues and printing textbooks for home study (about 850 pages). After about 650 pages, I noticed that there was significantly less toner in the black. The claimed toner is said to print up to 3000 black pages. I emailed the company and received a response within 24 hours with recommendations, questions, and an interested support rep. After sending photos of what I had printed (a sample set) and trying to get recommendations, I received another response that they would send a replacement set. No additional worries. Within about 72 hours I received several emails and a replacement product was sent to me. Thanks for the great customer support.
