I replaced my HP Officejet 5222 OEM cartridges with LDProducts cartridges. My printer ran really slowly. Took forever to get a page printed. And the printing was not good. Every 4th line was crazy. They would duplicate a letter or two and run down into the next line at the beginning or end of a line. I called customer service and was put on hold several times. I got no satisfaction and was told I had to mail their defective cartridges back before I would get a refund. It cost over $12 dollars to do that. I'll never buy from this company again and will tell all my friends of my experience. If I could give less than 1 star I would do that.
