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 Jose Baldwin

I've only used the black cartridge so far and I'm delighted - Installs in seconds - OEM cost share - Same/Perfect quality The only caveat is that Canon DRM reports it as a "counterfeit cartridge" which requires the grumpy screen that closes after each launch. But this is 100% the fault of a greedy printer manufacturer and applies to all non-OEM cartridges. I will definitely buy more!
