At first I also thought that these cartridges are a bargain and was delighted, although some compromises had to make in the print quality. But now my printer nozzles are clogged, that they are no longer to clean. And after I have replaced the cartridges once, so do not yet have so long in use. The printer almost no longer prints, I have to throw it away. I can not explain the fact that these cartridges have clogged the nozzles only. So all in all, unfortunately, an expensive business. I would absolutely not recommend the purchase.
