I don't think I'll be using regular ink anymore. These inks work just as well as the big brands! I have an Epson Workforce 545. I'm a private tutor so I do a lot of printing and use an insane amount of ink. It was a great and cheap alternative. I only had one problem. I noticed that when I printed multiple copies, there were black spots in the corners of the paper. But as soon as I printed it out one by one, it stopped. I tried cleaning the injector but the problem persists. But that only happened once when I printed 25 copies. In fact, I've just ordered this product again, it took a while, especially with the amount I print.
