This ink should last longer than a full sized ink cartridge but it didn't last as long as a full sized ink cartridge. I don't print a lot of material before the tax period and after 2 months of minimum usage I have to reorder. I didn't even use half of the 500 sheet ream and many of my prints used minimal ink. I am ordering 2 packs of normal size ink cartridges. I'll have a backup if I suddenly run out of ink and had a separate cartridge that lasted longer than this one.
