Although not official HP ink, once installed the printer recalibrated and accepted the ink. No noticeable change in print quality. Great price.

Thank you for this terrific product, and the quick turnaround time from ordering date to delivery was much apprecited!

So far, so good. Only time will tell.

So far the cartridges work. See how long-they last
