So, March 2017 I ordered 3 high-yield cartridges for my printed. These worked great, and got me through over a year of printing while occasionally working from home. Fast forward to July 2018. I run out of my last cartridge, so I got back onto their website, login into my account, and reorder the same cartridge from my purchase history. Not only did those three cartridges not work, but the six replacements sent do not work. The cartridge does not look the same either. So now I have 9 cartridges sitting on my desk, none of them working, and black hands from the ink. Disappointed to say the least. I wouldn't bother ordering from them unless you have a TON of time to test cartridges.
