Review on Uniwork Replacement Toner Cartridge for Canon 045/045H - 4 Pack by Erik Haynes

I bought these for the Canon MF634Cdw. These are good cartridges and I haven't noticed any problems so far. I installed them with original Canon cartridges with no compatibility issues. The print quality does not differ from original cartridges. My only criticism of this manufacturer is that the instructions were not very clear. The pictures in the instructions were very generic and I had to fiddle around a bit when installing one of these cartridges for the first time. There are plastic tabs that must be pulled out before removing the plastic seal from the rollers on the cartridge. While I find that they are still a bit pricey for cartridges from other manufacturers, they still save you money compared to OEM replacements. Knowing they work well I wouldn't hesitate to buy them again in the future.
