Review on 🖨️ GPC Image Compatible Ink Cartridge Replacement for Canon PGI-270 271 PIXMA MG6820 MG6821 MG7720 MG5720 MG5722 TS6020 Printer Tray, 12 Pack - PGBK, Black, Cyan, Magenta, Yellow by Maurice Harvey

I love this ink. My printer works without any problems. I don't get any weird codes that I get with other brands of ink. Also, because of the transparent plastic, I can tell when the ink is gone. Canon OEM ink contains a sponge material inside that hides the actual ink level. Yes, you can use Printer Utility to determine ink levels, but it is not accurate. Buy these ink cartridges instead.
