What can you write great about original ink cartridges from Canon? They function properly, at least mostly. The really extremely high price has been mentioned here several times and I can only repeat again. That's just too much money for very little ink! In addition, my Canon printer Pixma MG 6250 squandered the ink literally. In a review could read, he is a "print head cleaning machine" with print and copy function. The is really nothing to add!
