EBBO Compatible Ink Cartridges Replacement for HP 934 XL 935 XL Ink, Work with HP OfficeJet Pro 6830 6230 6815 6812 6835 6820 6220 Printer, 4-Pack (Black, Cyan, Magenta, Yellow)

These worked perfectly with my printer. Sometimes a box pops up when I'm printing to let me know they aren't HP cartridges, but I just cancel out of it and everything prints just fine! I will be continuously purchasing these. I also did not have any issues with the cartridges leaking or dropping ink when I opened the seals. Just don't squeeze as you are removing the orange tags and they won't spill. These are great. I am so glad I can find an affordable option for my print cartridges because I use mine for business and print a lot.

We're on our fourth set of refills and even when my HP-6830 didn't like them, the vendor replaced them quickly with ones compliant with HP technodiscrimination.As we understand it, many printers are sold at really low prices expecting to make it all back on the cartridges, HP among them.So instead of just accepting every cartridge that works --including these recycled and refilled ones-- they try to lock out all but "Genuine HP Cartridges", the error message that comes up a few percent of the time.But just contact Amazon or (better still) the manufacturer directly and they promptly and courteously replace

got tired of paying high prices for HP Print Cartridges...decided to give this brand a try and thus far extremely happy with the quality of the print that I am receiving. Have tried other off brands in the past with very mixed results, but will re-buy again when needed. This set of print cartridges were 1/3 the cost of OEM HP Cartridges! Have had no problems thus far.

I ordered replacement cartridges for my HP printer and I wasn't disappointed at all. In fact, I tested out a color page and the color is fantastic. I couldn't tell the difference. Will order again.

I was hesitant to try ink from another vendor other than the printer manufacturer. So glad I did! It is working just fine for me and the cost can't be beat! I will order again.

I have tried several refill shops for ink because I can not justify spending $80 on new ink from Office Depot or other sites so I tried this. I can not believe the quality of this ink! I must have printed at least 100 color copies last night and still have no "low ink" warning on my printer. I am so happy that i found this ink at this price!! I just want to print everything now because I can ;)

I must admit EBBO'S customer service is consistently striving to make sure their customers are satisfied. I assure you of you buy this product you will save a lot of money. They actually work just as well as the HP cartridges. I do have to about three red isn't quite as dark as HP'S but it is functional. This is there only negative I can say about this product. They work flawlessly without having to download any software updates for your printer as you have to with some other brands. Thank you to EBBO customer support fire job well done.I attempted to review this product but Amazon chose to deny my first review so I am attempting to try again. I ordered this product only to receive it defective. The black cartridge wasn't put together too well as it wasn't sealed properly. The case looked deformed. I have chosen to return it but as the cartridges looked so strikingly like the original HP cartridges I have decided to give it another try. If the second order goes better than the first then I will amend my review.

Works well in printer. Black cartridge had a lot of liquid underneath the cap.From customer support : Be sure to pull tab on top first. Then turn upside down for 5 minutes. Then open orange cap and install. Any extra ink should be wiped off before installing.
