Works as advertised....not much more I can say!

Again inks are great. I am not sure the grey has improved output quality though. It simply causes me to have to buy the extra ink. The XL tanks including this extra grey do not seem to last any longer with similar usage pattern before I having to purchase again, sometimes from the bricks and mortar store if I don’t have a moustache brand backup on hand. The XL tanks used to last me almost a whole year. Problem may be having to print nozzle test when tank Is empty but indicator says full..

This grey ink Cartridge had to be purchased for printer to work. I thought that grey would improve print quality or capability. I have seen no improvement or difference between a 6 cartridge and 5 cartridge printer with this grey tank added. It just seems like an added expense for nothing. But no complaints about the inks themselves in general, or the 123ink company. 13ink are quite responsive to problems.

As advertised...what else to say?

Not part of the bundle required for pixma 7720, so you need to scroll around to find the grey tank. Good service overall for all orders thus far.

Great value
