Review on HP Cartridge CC640WN Deskjet Photosmart by Nathan Tank

These black HP ink cartridges came in a pack of 2. The first cartridge was ok and worked great. This went from January when I ordered them to today, May 7th. The second cartridge was defective. It didn't even print an alignment page. The packaging was sealed until I opened it just before installing it in my printer so I don't know how but it looks like it didn't have enough ink. Now it's too late for me to return it and get a refund. So I'm very dissatisfied!
