Review on 🖨️ Smart Ink Compatible Ink Cartridge Replacement: Canon Pixma PGI 270XL 270 XL CLI 271 271XL (PGBK&BK/C/M/Y/GY 6 Pack Combo) for MG7720 TS9020 TS8020 by Ken Barnett

Just replaced the 271 black cartridge in my 7720 with one of these. After some thought, the printer displayed a message about an original Canon cartridge. Did a few everyday prints and everything worked fine - the print looked good. I haven't tried color cartridges, small or photo prints yet. Also, durability and performance over time have yet to be tested, hence the 4 stars. If they work and hold up over time, it's definitely 5 stars. Update 10/2019. I tried printing the photo on glossy photo paper with only the large black cartridge installed (the rest are genuine Canon cartridges). The results were terrible. The black ink was smudged and didn't dry completely. Still streaks after a week. It seems to print well on standard paper as the paper absorbs ink. I am going to replace it with an original Canon cartridge because I want to be able to switch from text to photo printing without changing cartridges. If you're not shooting or are willing to change cartridges in the process, I think they will work.
