Review on E-Z Ink (TM) Compatible Toner Cartridge Replacement for Canon 128 CRG128 3500B001AA, for Enhanced Performance with ImageClass D530 (Black, 2 Pack) by Adam Quintana

Bought two packs. Both cartridges initially printed well, but both suffered from print quality degradation before the toner ran out. Both cartridges leaked toner at the ends, which collected on the drum and left a gray streak on both ends of the paper. Both cartridges printed a good number of pages, so I can't complain about the poor value for money. But I would like to be able to use the toner before changing the cartridge.
