Review on E-Z Ink (TM) Compatible Ink Cartridge Replacement for Canon PGI-250XL PGI 250 XL CLI-251XL CLI 251 XL - Pixma IP8720 (6 Pack: 1 Lg Black, 1 Cyan, 1 Magenta, 1 Yellow, 1 Sm Black, 1 Gray) by Jeremy Keller

I've read about common cartridges that have identification problems when the printer doesn't recognize the cartridge, so I was relieved when the printer recognized the gray cartridge straight away. The quality of the printed image is also good. I liked the ability to order the same colors as the cartridges in the printer. That way I have a backup supply of cartridges when I use them. I can order multiple colors of the same color if I see a usage pattern. I just replaced the gray one and it looks like there are two more that need to be replaced. Most of the time I prefer to use my laser printers because they are always cheaper to use. Fortunately, the low price of these cartridges makes inkjet printers more affordable when color printing is required.
