The XL cartridge fits our HP Officeject 6850 perfectly. The printer recognized it as non-HP ink, but there is no issue in printing. Clean black and white prints for general at home use.

Defective item there is no Inc. in the cartridge

Its ink and it works..cartridge slightly larger than others

Works great! No problems

Your brand of ink is the only one that doesn't display the "damaged ink cartridge" warning on my HP printer. All the other brands, I had open up the printer and adjust the cartridges to get the HP to print.

Works great, excellent price.

Using these ruined my print head. Printer is now worthless.
