I have bought several of these cartridges. I don't feel like I get as many pages from them as I do from original HP inks (just by feel). I just ran out of color ink and the first Retch ink cartridge had an error and didn't work with my printer. I have cleaned the printer and cartridge and tried 4 or 5 times but it never worked. This was a cartridge I've had for almost a year (I don't run out of color ink very quickly) but it was sealed so I expected it to work. My printer knew right away it wasn't going to work, so I'm guessing it has something to do with an electrical component. Of course it's too late to ask for a replacement. From now on I use original HP inks.
