In my case, unfortunately, only special

At the time of my purchase, there was for this cartridge yet no reviews.
In this respect, lured the price and the promised information on the page seemed reputable.
Unfortunately, the cartridge turned out in my case as absolutely useless because it - defying the built-in chip - have not, or not recognized by the printer properly and also to put it in the printer even expired ink and so there was a danger consequential damages causing the print head.
I can clearly advise from above experience, from buying !!
The only consolation and mentioning positive: After somewhat laborious e-mail correspondence and "clear terms" For my part, took place at least a refund of the purchase price on Amazon.
To that extent I was only buying the - totally overpriced - original Lexmark cartridges. These perform their proper service now and hopefully keep for as long as it indicates the manufacturer. I'll see ....
