Review on Uniwork Replacement Toner Cartridge for Canon 045/045H - 4 Pack by John Boyce

Yes, they are much cheaper than genuine Canon brand toner cartridges, but the printer keeps complaining that they are "fake" and the printer cannot show the fill level. I guess it's not a big deal, but the constant appearance of these warnings is annoying. So far I have not had any print related issues with these toner cartridges and the print quality is the same as the starter toners that came with my printer. Fingers crossed they work or else I think this will prove to be a costly mistake.
