Review on COLORETTO Printer Ink Cartridge Replacement for Canon PG-240XXL, 240 XL & 240 XXL (2 Black) - Compatible with Pixma & MG Series Printers - Combo Pack by Aaron Franklin

Try as I might, I couldn't align one of the cartridges correctly. I've tried setting them up manually in the app a couple of times and it was enough to make them readable. The second cartridge worked well, just needed some tweaking. Unfortunately I need to print legible shipping labels so I'm keeping one working cartridge rather than returning both. Save time, just buy an OEM cartridge.
