Review on Valuetoner Compatible Toner Cartridge Set for Brother TN227 TN223 - MFC-L3770CDW HL-L3230CDW HL-L3290CDW HL-L3210CW MFC-L3710CW Printer (4 Pack) by Michael Hemmig

Update: Not working after return period. Like other brand. They also don't answer emails. Do not buy. I bought toner from "Authur Imaging" because it was recommended in my 3290 order but gave me an error message when I finally tried to refill it a year later. I was almost ready to buy Brother toner until I realized it was going to cost me about the same as the printer itself. So I decided to buy another brand just in case and it worked! I'm a student so thanks for saving me money. Incidentally, the color and consistency are comparable to Brother.
