Review on Arcon Replacement Toner Cartridges for Canon 045 045H CRG-045H Color ImageCLASS MF634Cdw MF632Cdw LBP612Cdw - 4 Pack by James Womble

The print quality appears to be good at a third of the price of the official cartridges, but I have noticed that the toner cartridges wobble a bit in the compartment. I checked and one of the tabs it holds on to is about 1/8 inch smaller than the official dolly. No mechanical issues so far but I'll keep an eye on it.
