Review on ejet Compatible Ink Cartridge Replacement for HP 564XL 564 XL - 15-Pack, High Yield Ink for Photosmart, Deskjet, and Officejet Printers by Demetrio Lowe

This is the second time I have bought these and they are still being used for all my ink needs. You make a big difference with super fast shipping. Not only that, they're easy to install and fit perfectly, and are made of clear plastic so you can see how much ink you have instead of guessing. They also print great right out of the box with no need to reprint faulty pages.
