Black Ink Cartridge for HP 564XL/ CB321WN/ CB316WN (Remanufactured) Product Purchased: June 15, 2011 The quality of the ink is fair for the price. However, you dont know how low the ink is until it is empty. This is because the HP printer is designed to recognize non-HP cartridges and not tell you what the ink level is. One more thing, when you open the ink it leaks so you have to be very careful when you open it. We were not aware of this and spent the day trying to get ink out of our carpet.
