Review on 🖨️ GPC Image Compatible Ink Cartridge Replacement for HP 564XL 564 XL - 4 Black Cartridges - DeskJet 3520/3522, OfficeJet 4620, Photosmart 5520/6510/7520/7525 Printer Tray by Tim Duncan

Compatible cartridges. I only had 1 cartridge that my printer would not accept. I downgraded it a bit because I seem to go through black ink like crazy. By crazy I mean within a day or two. But it's still good. Better than I have to go somewhere and it's still expensive to print. The print quality is excellent. No problem with that. I only wish I had passed like water. I bought other cartridges that lasted longer. Honestly, I'm a personal teacher. I type more than most.
