Review on High-Quality Smart Ink Compatible Cartridge Replacement for Canon PGI-250XL CLI-251XL - Ideal for PIXMA MX722 MX922 iP7220 iX6820 MG5420 MG5422 MG5520 MG5522 (1 PGBK & 1 BK/C/M/Y Combo Pack) by Kory Shelton

You know that, the ink runs out at the wrong moment and there are no cartridges in reserve. Well I thought I was ready this time. I bought a set of replacement cartridges compatible with Smart Ink. Unfortunately they (magent and cyan) didn't work. They were both rejected by my Canon TR8520 printer. what more can i say They didn't work as intended. It deserves a star in my book. Now I have to order the original from Revain. If it wasn't for the coronavirus era, I could just hop on the bus and be at Walmart in minutes. Unfortunately now is the time of the coronavirus and they can still sell out. I have successfully used unapproved cartridges in the past, but they were made by another company. I only bought it because of the many rave reviews.
