Review on Valuetoner Remanufactured Toner Cartridge Replacement for HP 305A 305X Printer (4-Pack) - CE410A CE410X CE411A CE412A CE413A, Compatible with Laserjet Pro 400 M451dn M451nw M475dn M475dw M451dw M375nw by Joseph Hamilton

Original on the right, value toner replacement on the left. I only replaced black and magenta because those two colors spotted my old cartridges at the same intervals (note the vertically running spots on the right - one column of black and one of magenta). Replacing these two cartridges removed the stain! However, a head-to-head comparison really shows how different the print quality is between the two. In particular, the most important representation of black text on a white background looks very pale compared to the original cassette, and in some places where the font is smaller, it is hardly legible. You can also see in the image where the magenta was much lighter and the whole image actually looks like it just got brightened in an image editor. For the money I really can't complain - all I expected from them was possibly to be functional, and they are. But if you want a faithful reproduction of the image, you'll probably have to spend about ten times as much for the original.
