Review on 🖨️ High-Quality Compatible Toner Cartridge for Brother TN227 TN227BK TN-227BK TN223BK (Black, 2-Pack) - Ideal for MFC-L3770CDW HL-L3290CDW HL-L3210CW HL-L3230CDW MFC-L3750CDW MFC-L3710CW Printers by Steve Cypert

Print quality is excellent but I am a little disappointed that my phone and computer tell me that the toner is running out after about 100 prints. My guess is that the connection between chip and printer is not perfect. I think I also have to guess what the lifespan of this toner will be. I'm glad my printer brother at least recognizes it and uses it to print. I assume based on other reviews that it will last a long time and still hope so.
