Great product for my monochrome hp printer. Don't waste your money on original toner from the manufacturer. If you print a lot of black and white, purchase a hp monochrome printer and this toner. Don't worry about non-geninue message on the printer, everything is ok. When you get a low toner message, you can get another 100 copies out of the toner if you shake the toner and you can continue for quiet a few pages until you really need to replace it finally, plus the excellent service from these guys.

Side note, the printer indicates that the toner is low somewhat prematurely.
