Some people say these don't last as long. I don't know if that is true or not. They seem to do just fine. However, even if that is true, do the math. These cost a fraction of the new ones. If they last 75% as long, you are coming out way ahead. And, they work great. My Firm used to order all the toner new, I have required them to use these instead. They work just as well and we have saved literally thousands of dollars. I have a bad experience with refilled toner, these aren't. They are remanufactured which means they work. Buy one, you won't go back to new ones. We now wait until we need a dozen or so to make the shipping more cost effective, but try one. Even with the shipping it is still a bargain.
