Review on GPC Image Compatible Ink Cartridges for Canon PGI-1200XL: Ultimate replacement pack for MAXIFY MB series printers (5-Pack, Black, Cyan, Magenta, Yellow) by Jason Nguyen

I used the black cartridge intensively for almost two weeks. There were no issues with clogged printheads or print quality degradation due to original factory inks. Everything seems to be working fine. I will update my review about a month after using all the colors and the second black ink cartridge. ****Update**** This ink has been in use for more than a month. My MB2720 still has no problems. No clogs, no color issues, no issues at all. The printer lasted up to a week and a half without use and printed flawlessly when I asked about it. I have not cleaned the printheads in the two months I have owned the printer. I would still recommend this GPC ink for the Canon MB2720. Update 3/29/18 - the ink still works fine. No clogs, no printhead problems, no printing problems in general. I haven't cleaned the print head yet. My only issue right now is that the price of this cartridge has increased by about $7 since my last purchase (I originally paid $17). Updated 06/16/18. The inks still work well and I haven't had any issues with these cartridges. I placed another order as the price dropped to $20. Update 01/11/19 - The printer is still working fine. Haven't cleaned the printhead in months. No issues with ink or print quality. I only use this ink for general everyday printing. I don't print photos or anything important. The price is less than $20, so I ordered more.
