Review on MIRHO Compatible Toner Cartridge Replacement – High-Quality TN223 TN227 Compatible with Brother Printers – 4-Pack (1 Black, 1 Cyan, 1 Yellow, 1 Magenta) – Perfect for HL-L3210CW, HL-L3230CDW, HL-L3270CDW, MFC-L3730CDN, DCP-L3510CDW by Ashutosh Takumatla

I thought it would work like TN221 but the numbers my printer actually used got confused. I gave this to my boss who has a printer brother who will be using it. These are aftermarket toners that I was hesitant to use given all the negative hype that can be around them. Aside from the case design and the name on the side, however, you wouldn't tell this once you open it. Easy installation and the cartridge will charge normally. The print quality is indistinguishable from a branded toner cartridge. I don't know how life will compare but if my boss tells me it's shorter I'll come back and update my review.
