Review on MM MUCH & MORE Canon 045H 045 CRG-045H Toner Cartridge Set for MF634Cdw MF632Cdw LBP612Cdw Printers (4-Pack, Black, Cyan, Magenta, Yellow) by Douglas Norton

This was the cheapest toner kit I could find so I took a chance and bought this one and looks like it would be a good choice. I purchased this kit specifically to replace the K cartridge for My Canon MF634cdw and so far it has produced high quality prints. There are no obvious differences in print quality between this cartridge and the real 045 pistol. I will update my review again once I start using color toner. Judging only by the properties of the K toner; Color toners should work just as well. 6 month update I have been using these cartridges for about 6 months and I am sorry to report that they are not holding up well. The print quality has deteriorated significantly. This can be seen in the uneven distribution of ink throughout the printed document - some printed areas are lighter or darker than others. Also, very thin lines are visible on the printout. Unfortunately these issues have forced me to update my review to 3 runs (it's still a good deal and for the price you get what you pay for in terms of quality). Now I will look for another alternative to ink.
