I had zubächst great doubts about the quality and function of this cartridge set. They were immediately recognized by the printer (Pixma MG6150) and worked right away. It may be that the color is a little paler than the originals are, but all 6 cartridges together cost 3 euros less than 1 (one) of 526 cartridges of Canon. I call that a savings. I can only recommend this cartridge set!
