Smart Ink Compatible Ink Cartridges Replacement for HP 934 and 935 HP 934XL 935XL 4 Combo Pack (1 Black, Cyan/Magenta/Yellow) for HP Printer Officejet Pro 6230 6830 6835 Officejet 6800 6812 6815 6820

Just as good as HP at half the cost. I have no problems so far and I installed them with ease with no leaking problems. My printer did warn me about compatibility but they are working just fine with no issues.

After years of purchasing name brand ink I decided to give value priced ink another try. I decided to buy a set of Smart Ink 934XL black and 935XL CMY for my HP Officejet Pro. I had to wait several weeks for my old HP cartridges to be used up. Didn't have to print much at the time. The Smart Ink 935XL cyan cartridge was the first to go in. I installed and followed the included instructions. Worked without any issues. Print quality was good. I was relieved it worked right off the bat. A month later I installed the Smart Ink 934XL black cartridge. Followed the instructions and again printed without issues. The magenta was the next cartridge to be replaced. I installed and followed the instructions. This time the magenta didn't print right away. After performing a level 2 print head cleaning it worked. No big deal. The instructions mentioned this maybe needed. Our house go days without needing to make a color print. During long spans of no color prints the Smart Ink 935XL magenta would again stop printing. It would resume printing only after a level 2 print head cleaning. This occurred a few times. After the 3rd time I realized it wasn't going to get better. All of the print head cleanings was using/wasting the ink. At 9pm on a Sunday I reached out to customer service via chat at https://smartink.pro/us/. After a few minutes of confirming my print problem they sent me a replacement cartridge with expedited shipping. The replacement Smart Ink 935Xl magenta worked right away without an issue. The fact that 1 of 3 cartridges (haven't needed to replace the yellow yet) from my purchase had an issue was a bummer, but how Smart Ink Customer Service quickly resolved my issue is terrific. They do stand by their product. I would definitely buy again and would recommend this brand to others.

Good price, good alternative. Although my printer at first did not want to recognize it, so far it has worked for me for documents that does not require much print quality.

First black cartridge didn’t work. I called the support number and the gentleman walked me through a couple of tests. Then said he would send a new cartridge no charge. It arrived two days later and worked perfectly. Quality product and great customer service.

They do NOT work!!!! The only color that printed was a slight yellow!

Excellent. Perfect quality. Works great with my printer . Great value. Ink last a long time.. even better thank the original HP ink. Will buy again

The toner cartridges were easy to install and worked as they should.

I needed cartridges again for my HP printer and was shocked at the price for brand name so I went looking for alternatives. This set of four was a good price and seemed to have the best reviews, but I was still very skeptical about taking the leap. I even waited several days before installing them and debated if I would return unopened. However, it could not have gone better. The cartridges were nicely packaged, installed easily, and I'm happy about the quality. Will definitely buy again!

Good Cartridges

I have recently installed Smart Ink on my HP6830 the message "non genuine HP ink cartridges detected" pops up which is expected and obvious however what i did not expect is when i tried to print colored documents colors were off ex: red comes out more like dark-ish pink , blue comes out a very light purple hence why i would not recommend this item !

مايسوى ريال مايطبع الا اصفر حرام الفلوس اللي راحت فيه

One of the ones was not recognised at 1st, but I spoke to the smart ink chat who sorted it straight away! This ink is almost a 10th of the price of HP so well worth it.
