I thought there was no way on earth that I could get TWO cartridges for a fraction of the price of one and that it would work and be okay. Well, I am glad I took a risk, because it is totally legit! I have been using these for a few weeks now, and my print quality shows no change from the name brand toner tank. It was easy to install and I had zero issues with that end of things. It was "accepted" by the printer, and has been printing clean and sharp. Two thumbs WAY up!
