Review on 🖨️ Toner Bank 5-Pack TN227 TN-227 Compatible Toner Cartridge Replacement for Brother MFC-L3770CDW HL-L3270CDW HL-L3210CW HL-L3290CDW HL-L3230CDW MFC-L3710CW MFC-L3750CDW Printer - TN227BK TN223BK by Alex Ferry

no problems with the black cartridge so far. Prints just as well as the original cartridge. The packaging was solid and included simple installation instructions. The photo, along with the packaging and instructions, shows the cap from an unused cartridge. I only used this to cover up the used one to throw away. Great product at a great price. Will buy again. I'll try to remember to upgrade when using color cartridges as I don't need them yet.
