Review on 🖨️ Cool Toner Compatible CE278A Toner Cartridge - HP Laserjet P1606dn 1536dnf MFP M1536dnf - 2-Pack Black Ink by Jason Clemons

They are very nicely packaged and easy to install. I have an HP 1606 and do a lot of duplex printing. The print quality is excellent. I've tried 3 types of "enhanced" cartridges and although I don't count the pages, none of them actually print 2100 pages. The number of pages varies, of course. These cartridges work as well or even better than others I've tried, but cost a lot less. That's why I keep buying them. After all, they are just as good or even better than others I've tried, nicely packaged and cheaper. I will continue to buy them.
