DOUBLE D 934 and 935 Ink Cartridges Compatible Replacement for HP 934XL 935XL for HP Officejet Pro 6830 6230 6815 6835 6812 6820 6220 6810 Printers (2 BK,1 C,1 M,1 Y, 5Pack)

Like all other 3rd party cartridges, the HP printer does its best to reject them, with 'missing or damaged' error messages.My recommendation is to replace just one cartridge at a time; you will have to remove and reinsert them each 3-6 times before the printer grudgingly acknowledges they are not original and allows the final setup to proceed.So it will take 10+ minutes to get all 4 replacement cartridges working, after which they behave just like authentic HP ones, but at a very small fraction of the cost.Unlike some other 3rd party cartridges I have used there is no leaking or smearing, and print quality seems high.I cannot justify paying almost $100 for genuine HP cartridges to put in a 4+ year old printer that cost around $120, and neither should you.

My HP printer is still operational after I ordered the replacement cartridge. Prints well and installs easily.

This is often hot or miss.Not always true color.Great value for $$

This product will NOT work in a HP 6968 printer, it has a short return period. I have used it for several years and have not updated the printer and these latest cartridges will not work. The only reason I gave it a star is so that it would except my review

These ink cartridges seem to last forever!! The ink is great quality and gives vibrant prints that have fast drying pigment. No wet or wavy sheets here! I always get over 1000 prints before I am alerted of low ink. Did I mention the chip technology? I love the chip system which makes it easy to install and refill. I can see when the ink is running low and can purchase a new pack without waiting until my pages print with streaks. The cartridges store well and are vacuum sealed with material that doesn’t absorb light so that the colors remain high quality on the shelf. I highly recommend these. They fit in my HP printer. The shipping is fast and convenient.

It works great and less expensive than others

its not from HP, so i will buy it again for my printer. Prints well and fits well in my printer with no issues to report. I haven't had it long enough to see if it has longevity, but i'm not worried about that.

Bought this product a few times, so far everything works fine in my copier

Took some time to adjust but after few tries it worked

Rubbish

Was skeptic about this, but thought I will just try it out.The cartridge was not recognised at first. After a few times to remove and install, it was finally accepted and it works!
