I print a lot so I love the XL size option for Canon ink cartridges. At first I was a bit puzzled why the black 251 cartridge wasn't included, but the printer really doesn't use much of that ink. I regularly use PGI 250XL black cartridges, but not 251, so bundling these cartridges into an XL size is very useful and reduces the cost of printing a bit. The colors are beautiful and the print quality from the MX-922 is really good. I am very satisfied with both the ink and the printer.
