Review on 🖨️ Sotek Compatible Ink Cartridge Replacement for Photosmart 7520, 6520, 5520 - High Quality 564XL Ink (12 Pack) by Jack Edwards

Before purchasing this HP 564XL and Photo Black bundle for my HP Photosmart 7520 I read the feedback from these customers. Gave 5* and good comments. So I ordered it. After I put it in my printer, it doesn't work! I've tried many times! I still can't! So I opened another and opened another! By the time all 4 black inks have opened, 2 other colors have also opened. Still nobody could work!
