My first review was that this is the worst printer ink. The print was not as fine as Cannon's ink, making the letters blurry and bold; and he left black streaks on the sides and front. However, after a few weeks of use, the spots and lines are gone. The quality is ok. So if you order this product, expect a bad experience for a few weeks and then better results will follow. Before that I always used Cannon and never had a problem. Putting up with initially poor output quality for a few weeks can be worth half the price.
