Review on V4INK 2PK Compatible Toner Cartridge - Canon 120 CRG-120 High Yield Ink for ImageCLASS D1100 D1120 D1320 D1350 D1150 D1180 D1170 D1370 MF6680DN Printer by Mike Hicks

I bought 2 of these in December and finally started using them in February. It's now 2 days after the return date and I'm stuck with 2 ink cartridges that don't work because they jam the printer when trying to print. When I put in a premium brand toner cartridge (also bought from Amazon) the printer works fine. Then I go back and paste v4ink and it clogs the printer again. There are other vendors that sell this cartridge and I've had better luck with them. Shame on me for cheating, shame on you v4ink for making a poor quality product.
