For over it is, finally, it has a large capacity, and it saves on the cost to the page, and as the most that work with Lexmark are saving ink (look on the internet you will see), c is a good choice.
Packaging is pro, the cartridge is well protected, easy to insert.
In addition if you go on the Lexmark site, by simply giving your address, they send you lots of little bag freed to return their used cartridges: it's really nice not having to take the lead for recycling!
