Review on High-Quality Kingway Compatible Ink Cartridge Replacement for Canon 280 281 XXL PGI-280XXL CLI-281XXL for Pixma TR8520 TS6220 TS6320 TR7520 TS6120 TS9120 TS8120 TS8220 TS8320 Printer, (PGBK Black C M Y,5 Pack) by Miguel Escobar

No problem installing these cartridges in my Canon TR8520 printer. As usual, you have to be a bit careful when removing the tape covering the ink part of the cartridge, otherwise you will get the ink on your fingers. The same applies to branded cartridges. Pretty good value for money, but Kingway is probably paying Canon the right to make them, or they're even cheaper than replacement cartridges for older printers.
