I am being pressured to write this review. I do so reluctantly because it won't much please the producer (but may be useful nevertheless). I ordered the inks based on the Amazon name and the price. I received my package promptly. I have returned my inks, because the cartridge I was replacing was not 'recognised' by my machine. The instructions tell me to do all kinds of things, starting with removing all my other cartridges, climbing under my desk to turn off at the wall etc. I am not prepared to discard my other inks that work perfectly well. However I did make sure all cartridges were fully located in their slots.I have used other inks before - no problem (except clogging in one case). If I can't buy an ink that doesn't slot in and work first time, I'm sorry, I'm not interested. Moreinks try to be helpful. They clearly anticipate problems given the list of instructions if problems are encountered. My regular supplier(s)appear to anticipate no problems and their aren't any.Perhaps my set up is quirky. Oh, and by the way, I have had no acknowledgement yet of my returned inks.
