Good so far.

Si es muy Buena tinta trabaja muy bien

Works without issue in my Canon Printer/Copier. Good value.

My experience with Canon MAXIFY GX7021 Compatible Inks has been great! After several months of use, I can confidently say that this is a high-quality product with excellent performance.The package contains 4 GI-26 inks in black and color, which guarantees me a long life without worrying about running out of ink during the most important printing process. Each toner is designed for high page counts, up to 9000 pages (Of course, this needs to be decided in relation to the actual print surface).

UPDATE: I'm revising my review & increasing stars because I've solved the problem but the problem DID still happen so be warned. The good news is the damage was not permanent but it was still a huge hassle & I wasted 1 whole bottle of this ink PLUS 1 whole bottle of real Canon black ink AND 2 maintenance cartridges trying to fix this mess. Head clean did not help. Deep clean did not help. Ink flush did not help. (Ended up flushing entire tank of this ink then filling with genuine ink trying to fix it to no avail) Replacing maintenance cartridge did not help. I went so far as to order another printer so we had one to use while this one was out for repair. Out of desperation while waiting for that one to arrive I happened upon a how to video about manually cleaning the print head where they flush fluid thru it & looked like a real mess. I did the nozzle check, pulled the power cord mid way to stop the print head. Followed the steps to unlock & remove the print head and WOW was it gunked up! It was a gooey awful mess! I should have taken pics but it took multiple paper towels to wipe the goo off until it was clean. I didn't have the kit to flush so I put it back in then did a nozzle check & IT WAS FIXED! So yeah not sure I'll use this ink further or not (I may though since I had used multiple bottles without issue.. Maybe it just needs the effort of wiping off the printhead every few months..) but I'm just relieved it was a simple (messy) fix even if I wasted so much time & money figuring out. Hopefully this review helps someone else though.Original review: Bought these and they worked fine so I've been buying them multiple times since but this last batch is causing clogging where cleaning won't even went fix. very frustrating since tank is full and getting horizontal bands on my printer that's less than a year old. we print daily so definitely not issue of sitting. guess I'm looking for different brand or going back to original official ink. horrible print quality now

Works well with my Canon printer - no problems filling the tanks.General office use...

GARBAGE! Gummed up the printer head and ruined my printer. I saved a few bucks on cheap ink. It cost me a $750 printer.

This ink worked perfectly in my Canon Maxify printer. Same quality as the manufacturers at a fraction of the price. Easy to install, with no mess.
