- Seems to work as good as the original at half the cost.
It appears (and I can't be certain because every print job is different) that these cartridges may last a little bit less than the originals, however still offers an amazing saving on the originals. I have tried other compatibles that were not as good.
HP say or infer their warranty is invalid if use non HP ink. They can't get away with that so don't worry, if you get your ink from a reputable supply.
