Been looking for this sort of device for my Pantech laser.
The cartridge is good for 1,600 pages - no more, no less.
All well and good, they’re cheap, except.. the vast majority of my printing is in A5 size (roughly half-letter, or exactly half-A4).
Those half pages count just like any other page against the total, and I get shorted by the better part of 800 pages or so.
