This was the best liquid ink invention that could have been created! It was easy came with syringes and instructions. And was a perfect fit for my Epson wf-7720

I couldn’t use these because my printer broke - but these seemed to work well! I would recommend these to those looking to print

Ink would not flow and print. I found that laying a napkin under print head, and pushing air through the air chamber hole to push some of the ink through fixed the problem... Do it at your own risk and look up tutorials. Other than that, The cartridges are good.

This is not my first time buying these types of cartridges, it is however my first time having issues. As soon as these were put in the error message came up. I used an eraser as per the instructions and there was no option to contact the seller for assistance.

They work well but they don't tell you that you need the chip resetter for them to work

So I've done this a million times. But these cartridges the air and ink hole plugs are purposely put in the wrong hole. The clear is ink refill after you fill it you place the color plug in the refill spot. It's always been clear air hole colored ink they do it backwards. I just wish I had seen the video first. I just loaded the cartridges in and am print head cleaning so far I'd buy these again.The cartridges wouldn't auto reset when they said empty

I wanted too used in my Hp Workforce7610 , just didn't work .

I had to watch a few YouTube videos to learn how to install the ink. The cartridge fit my WF 7720 perfectly and I had no issues with the chip reading and resetting the ink levels. I wish it had better instructions. Be sure to fill the ink and remove the color tabs and close the hole you put the ink through.
