Review on GPC Image - Canon 045 045H CRG-045H CRG-045 Toner Cartridge 🖨️ Replacement - Compatible with Color ImageCLASS MF634Cdw MF632Cdw LBP612Cdw MF632 MF634 - 4-Pack by Jane Johnson

I was a little skeptical about using anything other than a Cannon toner in my MF634C but decided to give it a try. The installation instructions were very clear. Once installed, it didn't seem to recognize the carts as it didn't indicate they were full. Following her instructions to open the toner tray and then turn off the printer, reinsert the tray, wait 2 minutes and turn the power back on, all the carts showed full. So I'm happy at the moment. I don't know about the durability but I hope they work well.
