Review on Cool Toner Compatible Cartridge Laserjet by Eric Fish

The 4 pack black cartridge for our laser inkjet printer has started leaking through all the other cartridges and I am not happy. At the moment I would like to return these 4 packs as all the cartridges are sprinkled black. I used remanufactured cartridges in my previous order, no problem. And now the blue color flows everywhere and the yellow indicates a malfunction. They did not come in a cold toner box. Like another brand.
