This is a good product. The ink works very well. However, about half the time (or more), my printer does not recognize the ink cartridge and displays an error. When this happens, I have to take it out and put it back in, often multiple times. I do not know of a way to fix this. It caused an error so the document in the printing cue froze and will not cancel, making my printer unable to print anything. If not for this problem, I would give the ink cartridge 5 stars.
I wished I could have identified my PhotoSmart printer with this cartridge. The price is the same as with HP ($39.99 with free delivery), but it took a week to receive it. Next time I will come to Amazon. Still an expensive ink cartridge for 600 pages, but there is nothing I can do but to change printer.
