The cartridges Pelikan work - as opposed to a no-name product that I had previously used - very good on my SX105. Once the capacity is significantly lower than the original cartridges with 9 ml more than twice as large (colors) and almost twice as large (black) and the price, there is an enormous savings in costs. Only the ink level information is not always reliable and the printing stops unexpectedly under certain circumstances, but you get used to and can buy more time Reserve. This product is recommended.
