Review on High-Quality Smart Ink Compatible Cartridge Replacement for Canon PGI-250XL CLI-251XL - Ideal for PIXMA MX722 MX922 iP7220 iX6820 MG5420 MG5422 MG5520 MG5522 (1 PGBK & 1 BK/C/M/Y Combo Pack) by Julius Robinson

These cartridges are incredibly good value for money. Of course I have yet to find out if these XL machines will print as many photos as the Canon and don't know if the prints will last as long without fading, but so far so good. I had no trouble installing it on my Canon MG7520 and the brightness and quality are consistent with those made with Canon inks. It is recommended to change all colors at once, but I have not done this and prints with a mix of cartridges have come out superb. I have a question - do they make a gray cartridge?
