No worries
Ordered to go into a Brother DCP-J4120DW.
The cartridges announce 1200 pages, by experience I confirm this figure, in any case we exceed 1000 pages so nothing to do with other manufacturers.
Easy to set up.
The price I would say is correct considering the number of pages. I knew more expensive cartridges and that it was necessary to change after 50 pages printed so it is even squarely correct ^^
