So far so good. Needed to replace the black toner cartridge on my Canon printer, and this was the most economical option. I was leery at first, knowing that I have had problems with aftermarket cartridges in the past. But I have been pleasantly surprised that this cartridge did not throw any codes, was easy to swap out, and has provided quality printing thus far without streaking, blurring or patchy areas. As for it's longevity, only time will tell, but it looks like it will last at least as long as the OEM.

My old toner started leaking. This has preformed perfectly! If anything changes I’ll let you know.

The 1st cartridge of this 2-pack started streaking on the right side of the printed page 3 weeks after installation. The printer showed it was only 80% used. Installing the 2nd cartridge cleared the problem. After another 3 weeks, the 2nd cartridge caused black streaks on the left side of the printed page. Printer showed the cartridge was 90% used.

Great value for money. Easy to install, excellent print quality, no leakage eand the print quality is just as good as the original Canon cartridge.

This perfectly priced toner set continues to perform just as good as the name brand toners. If you follow the instructions of shaking the toner side to side, you will not see streak marks in your prints if printing on good quality laser printer paper. The color quality is amazing. I am always pleased with the way my programs turn out.
