High-Quality SOL Compatible Toner Cartridge Replacement for HP 643A (Cyan) - Reliable Printing for Office & Home Use

Have had these for some months now and have been changing them out over time as each color runs out. No problems at all. Great value! I do suggest that you test them ALL when you receive them in case there is a problem with one, so you can return it for exchange before Amazon's time limit runs out.June 2016 update. Magenta cartridge has 70% toner left, but the internal wiper failed, leaving magenta streaks on print. Had to buy ANOTHER replacement from a different re-manufacturer.
