Like all Lexmark cartridges the number of pages you can print, even on draft quality, is abyssmal. The printers are good but the cartridges represent dreadful value and if you do more than the smallest amount of printing you are forever re-ordering expensive cartridges and running out of ink half way through a job.
Definately the most expensive and disappointing cartridges have ever had and would never buy another Lexmark as a result (back to HP next time !)
ps refilled cartridges do not work on Lexmark printers - what a waste of resources.
