After much skepticism, I have now but buy the cartridges for the Canon Pixma MG5550 for my acquaintances. The last out of a shop with refill station were all unusable. After a very short time all began again at the flash. Now she has this in it. Were immediately recognized and she now has already printed up some. So far, no complaints have come. Both images in print and SW pressure she's thrilled. So rather providers keep them in range several reorders rest assured. Many Thanks.
