Review on Cool Toner 055H Compatible Toner Cartridge Replacement for Canon: High-Quality Ink for Your Printer (Black Cyan Magenta Yellow, with Chip, 4-Pack) by Jesse Nell

works as advertised. There are streaks of yellow toner. The support team contacted me personally a month after the purchase. I told them about the strips and they sent me a replacement free of charge. Now everything works great for a dime. I've lost the ability to check the amount of toner remaining in the cartridges and can't comment on durability yet, but so far so good. My printer is for my home office and family home school and this toner was part of the OEM toner replacement cost. Customer service deserves 5+ stars!
