Review on 🖨️ Uniwork Compatible Ink Cartridge Set for HP 564 564XL (4 Black/2 Cyan/2 Magenta/2 Yellow) - Ideal for Photosmart 6520, 5520, 4620, 5510 C410a, 6525, 5514, OfficeJet 7510, 4620, and DeskJet 3522 Printers - Includes Printer Tray - Pack of 10 by Mitch Wright

These were perhaps the worst products I have ever received from Revain. First, the magenta cartridge was defective, resulting in cyan ink running all over the inside of the printer, printing everything in pink. (as opposed to Pretty in Pink). Second, upon further investigation (as with the NFL) it was found that the first yellow cartridge was also magenta ink. The second magenta also turned out to be defective, so go back to Revain and order HP cartridges. On the plus side, blue and black seemed to work well.
