Review on GREENSKY Compatible Toner Cartridges for Canon 045 045H CRG-045H (4 Pack) - High-Quality Replacement for Canon Color ImageCLASS MF634Cdw, MF632Cdw, LBP612Cdw Laser Printers by Joshua Mejia

In the past my Canon compatible toner cartridges delivered slightly lighter blacks. As a result, my printouts were unsuitable for presentations of the thesis - only for drafts. So far I've only used the black cartridge from my kit. It delivered the darkest blacks I've ever had from a compatible toner. I am very happy to continue using it as it is (so far) the only compatible toner I have used that is indistinguishable from the OEM. I have been using the cartridge for about 1 month. I'll try to update this as I use other colors. I give a well deserved 5 stars for the print quality and the price. Not sure about durability yet, but I gave 5 stars so as not to penalize the product for not using it long enough.
