    Old Product Shipped
    While ordered as new and HP original, the box came mangled with massive amounts of tape holding it together, and had a sharpie writing on it date indicating a date of 2011 as if it was returned from another customer sometime in distant the past. It was even the old product model. Very dsiapppointing.

    5.0 out of 5 stars Nothing compares to the C9733A
    Reviewed in the United States on February 14, 2017
    Color: MagentaVerified Purchase
    This Hewlett Packard toner cartridge exceeded expectations! Constructed of rich black plastic, lovingly hand-crafted by machines and robots in Malaysia, this consumable delicacy produced print, like oil on canvas, in a color that could only be described as--not red, not pink...."MAGENTA".

    Since my purchase, I have been surrounded by beautiful women, sailed on yachts, eaten the finest caviar, and am rich beyond my wildest dreams!

    This product works great every time. I have spent over 8 years trying to use refurbished or knock off products like Xerox and have always had problems. Spend the extra money and go with OEM and you will save yourself having to ship back the remanufactured stuff.

    I received OEM cartridges as advertised. Have bought in the past cheaper refilled cartridges but they are horrible to work with, spilling powder all over the place. These were brand new tightly sealed cartridges.
