Review on 🖨️ E-Z Ink (TM) Compatible Gray Ink Cartridge Replacement for Canon CLI-251XL CLI 251 XL - Perfect for PIXMA MG6320, MG7120, MG7520, IP8720 - 3 Pack by Steven Guevara

Bought a pack of 3 EZ-Ink 251 XL Gray cartridges. The first one worked great, the print quality was fully OEM-compatible, I was thrilled. The next two were not recognized by my printer. One cartridge didn't seat, so I hoped after setting the clip, BUT it wasn't recognized either. Maybe it was defective chips? After several replacements, reboots, etc., I gave up and ordered another non-OEM brand, which worked right away. However, due to an important project, two cartridges were lost and printing stopped altogether. I used to be a big fan, now I've lost my faith. :-(
