I'd previously used recycled ink cartridges and it was fine so I hadn't expected to have any trouble - how wrong I was! I bought two inks - the first ran out almost instantly after some very streaky printing so I shrugged and wondered if it was a fluke or my printer & put the second one in - the first three pages were good then it started to streak again before (you guessed it) running out. Once again I went through the rigmarole of running printer calibration tests to no avail & decided the only true test would be to get an original hp ink & see if it was a fault with my printer. It wasn't. So don't buy these inks - they are a waste of money.
