These work just as well as the very expensive HP ones do.

These are working fine in my printer. The only thing is that the HP printers can recognize that there is a third party cartridge in there and will give you a one time warning the first time you use it after replacing it, but I have had no problems with them afterwards. The quality of the print seems equal and the seem to have a lot of ink in them, so I would expect them to last at least as long if not longer than a "genuine" cartridge, and they cost less than half the price of HP.

It works and it's cheap. Just have to press OK on the printer when it tells you that it's non HP INk. Can't really ask for much else. Thanks Monoprice.

I bought all four colors and Monoprice said the chip was revised for HP recognition, they were not, the printer gave me an error when I installed them. I believe the cartridges are still useable, but I have only just started using them.

Very fast shipping seem to work as good as the HP cartridges for much less

Good ink. Works fine. No issue with it not being OEM.

This works very well in the Office Jet 8600 printer. It does give a warning that it is not a "HP Cartridge", but it works fine. I have never had a problem with any of the cartridges I have purchased from Monoprice.

Used on HP Pro 8600. Did not recognize cartridge

PROS: good price

CONS: doesn't work

Received this item today. Printer does not recognize cartridge.

I received two of these cartridges and neither of them worked. Monoprice, like always is awesome and is going to refund me. Not sure why they didn't work. I ordered all the color too and only magenta worked.

CONS: Did not work
