Compared to the Canon original cartridges these ones are really tremendously low. Even the colors of her, I have nothing to complain about. My printer recognizes the tank thanks to chip immediately and without any problems. If one summarizes the cartridge during the opening at the corners, and does not press the side, runs out and no color. The ink, however, does not seem to be as waterproof as the originals. If you want to print package or letter stickers, one should consider that. A total of my 4 stars. I will order these things again.
