Review on Aztech Compatible Canon 055 055H Toner Cartridge Replacement for Canon Color ImageClass MF743Cdw MF741Cdw MF745Cdw LBP664Cdw MF743 Ink with Chip (4-Pack, Black Cyan Magenta Yellow) by Aaron Fowler

I like the print quality of these cartridges. The buyer should be aware that your copier will display "Warning Cartridge Not Approved" as it is not a branded copier cartridge. However, I haven't found any problems using them instead of "branded cartridges" and they're a lot cheaper! Glad I found them and will continue to use them.
