Review on Aztech Compatible Toner Cartridge 4-Pack for HP 201X 201A CF400X CF400A Color Pro MFP M277dw M252dw M277c6 CF401X CF402X CF403X M277 M252 Printer Ink (Black Cyan Yellow Magenta) by Jesse Gray

so far so good, cartridges fit and work well, no problems with hp printer, print quality is the same. Impressed that the cost was $140 less than a famous four cartridge brand. I loved that they came bundled so you got a full set of printer toners in one box and they say they are XL so I'm hoping to print lots and lots of these.
