I've used these inks for a while now................but I was tempted to the Dark Side in the form of compatibles that were about œ10 cheaper per set of four on Amazon. And of course, I might have got more satisfaction putting the money in a heap and torching it! They were rubbish and come what may, the printer would not recognise them. So, in the dustbin they went. The moral of this tale is:- stick with Inkrebile for top-notch, "never fail" ink supplies, and don't give the time of day to cheaper versions.
