Review on HP 935 Ink Cartridges for HP OfficeJet 6800 & Pro 6230 - Cyan Magenta Yellow - C2P20AN C2P21A C2P22AN by Wayne Flores

DO NOT BUY THESE. Of the three inks in the pack, one of the cartridges is "used, refilled, or counterfeit". The other two are readable with less than 20% ink. Nothing printed with these inks until I printed a test page to see if they worked because I got a low ink message and saw the supply level. The test page shows that the cartridges with allegedly 20% ink (magenta and yellow) do not work at all because the red areas on the printed image turned out to be black and white. Don't buy them, it's not worth the risk or hassle to get cartridges that don't even work, no ink in them and then have to send the faulty product back to get your money back. Instead, go to your local office supply store.
