There isn't much to say about toner cartridges, so I'll just answer the most important question potential buyers have: is the toner good quality? Answer: Yes, it is. I ordered it and received the right size on time. I bought it three months ago and have been using it in my printer ever since with no problems. Toner quality is good, print quality is good. (I've waited to leave a review to have time to use and evaluate the product.) Overall I'm very happy with my purchase and will definitely buy again when it's gone.
