I wanted to believe the reviews that had a good experience and hoped the others were just not following the instructions. While some of that is true I do believe, my color cartridge came defective, the cyan was either not refilled or was clogged or dried out. Due to this I was unable to run an alignment, which I believe caused some of the issues later. I was able to print maybe half of what I purchased the ink to print, went through several very invasive troubleshooting options, none of which worked and I ended up wasting more black ink and paper. My prints were distorted and blurry still till the end. The paperwork that came with the ink states that there is a 30 day warranty and 24/7 customer service, however there is zero contact information. The box I received was a completely blank brown box. I've reached out to the seller on here to see if they respond. If so I will update my review accordingly.
