Rated 5 out of 5 by tsavchap66 from HP inkI bought this a month ago and got free shipping for one day delivery, so when I needed a color ink cartridge (HP 22) I placed another ordered from the site with photo paper. [This review was collected as part of a promotion.]

Rated 5 out of 5 by Jerico55 from PrintersI'm not out of Black ink yet. But soon, I have it ready. 21's from Hp are the best. I highly recommend the 21 and the 22 color.

Rated 4 out of 5 by Msvb53 from Black inkI like that i can buy ink and have it delivered to my door a day later. I have seen that the cartridges do not have a full container of ink. And sometimes the color is more dark gray than black.

Rated 5 out of 5 by MisterE from Very blackWorks great. I put the cartridge in my printer, the printer makes it squirt on the paper, and presto! Words. Very black. Nice contrast with white paper. Top notch.
