When I wanted a refill for my Canon iP4600 printer from Amazon here, I'm scared at first whether the numerous negative reviews. That I can not understand that. Although the cartridges may certainly be greater, but at least one has ever to do it here with a system that allows changing of single color, and in which the cartridge is not replaced for all colors because of an empty color. And to my mind, the color ranges for roughly the same number of prints as with the previous models. I print out quite a lot of pick-up plates with large areas of color, and the need for ink cartridges remains limited. However, what I can recommend to anyone: If possible, take the multipacks, and always at least one, better to have two cartridges per color in stock at home! Otherwise it can be annoying because if the cartridges are empty, the printer refused any job. On the packaging, I like that there are only about two handles, then you have the cartridge one-click ready before him. Well done, I think. By the way, one more thing to the "ink critics": Given the very low prices probably every printer should be clear that the hardware be cross-subsidized through the expected consumption costs-profits. I would clear it, here bring an objective price comparison of manufacturers including consumption costs. However, I doubt now that Canon would cut as exceptionally bad.
