Review on DIGITONER Compatible TN450 High Yield Toner Cartridge 4-Pack for Brother Printers by Scott Yenson

One of the cartridges lasted less than 500 sheets of paper before the toner ran out. The first worked perfectly, but the second in the window was probably not filled out correctly. I cannot return Revain due to the time that has passed since purchase so buyers should be aware of this risk if they are not able to use and test both cartridges within the Revain allowed return period.
