Thought it would be more economical to buy the two cartridge pack. When I installed one of the cartridges I kept getting an error message that the cartridge was not the right size for my printer or was defective. My printer would not print or even recognize it as a new cartridge. So I tried the second cartridge in the package and it worked. Obviously one was defective. So much for trying to save money by buying two. Would have returned them both but needed to use my printer.
