I have bought from Amazon for many years and have never returned a single item due to inferiority. I bought both the black and color cartridges. The colors are absolutely terrible. Had to use some of it anyway due to necessity, however, I did return it. I thought maybe my printer was the culprit but after receiving my order from Staples, it printed beautifully. I have always had good service with Amazon however and hope they will issue me a refund.
