Samsung SV090A MLT-D309E High Yield Black Toner Cartridge (1-Pack) - Compatible with Samsung Printers for Office & Home Use

This toner is really good, does exactly what it says on the box.We tried using once a refill version once (Big mistake), half the toner ended up inside the machine and we had to get an engineer out, I would strongly recommend stocking to original Samsung toners.We usually buy the High yield but I honestly can't say if actually prints 30,000 pages.
