I use for years Accessories cartridges and have already tried some. As I have often been disappointed, I had no expectations for the riesiegen Hainsberger cartridges. But I was taught!
The cartridges hold high loose with the original Canon - at least as far as my claims. I print a lot of work-related - especially text documents in color and black and white, and graphics in documents.
The colors are brilliant, the ink dries quickly and the cartridges are in addition also still very productive. In my view, much more fruitful than the original.
Value for money: Unbeatable!
