E-Z Ink (TM Compatible Ink Cartridge Replacement for Canon PGI-280XXL PGI 280 XXL Compatible with PIXMA TR7520 TR8520 TS6120 TS6220 TS8120 TS8220 TS9120 TS9520 TS9521C Printer (4 Black)

Been using for about a year and havent had any trouble at all with them

Great product, works as advertised, good price, timely delivery.

Does what it is supposed to do for less. The ink is dark with no blotches or runs. Just like the original manufacturer Ink

Doesn’t seem to last as long as it should. I print almost entirely black.

This ink works fine in my cannon printer
