Review on 🖨️ S SMARTOMNI Compatible 270 271 XL Ink Cartridge Replacement for Canon PGI-270XL CLI-271XL, Works with PIXMA TS8020 TS9020 MG7720 - 1 Large Black, 1 Small Black, 1 Cyan, 1 Magenta, 1 Yellow, 1 Gray - 6-Pack by Shree Carmean

Tried this brand for Canon MG7720 for the first time. A day after delivery, the first cartridge I put in didn't light up or was not recognized by the printer. Tried several times without success. Very disappointed that it doesn't work right out of the box. Went back to Revain and had to temporarily reinstall an old empty cartridge to print something until I got another ink.
