Very disappointed! I bought two of these cartridges last year and the first one worked fine, but the ink ran out terribly quickly - I honestly remember only printing one image last year!). Recently replaced with a second one (doesn't print that often). Now my printer doesn't even work because it tells me I have a cartridge error. Very frustrating as I often have problems with ink cartridges and really wanted this one to work. All I can do is throw it away and buy a new one. I guess you never know what you're going to get unless you buy it direct from HP. Really freaked out.
