Review on Do it Wiser High Yield Toner Cartridge Replacement Set for Xerox Phaser 6510, 6510dn WorkCentre 6515, 6515dn Printers - Black, Cyan, Magenta, Yellow, 4-Pack by Isaiah Boys

I have just received these to replace the original manufacturer toner cartridges that came with the printer (model 6510). These replacement parts look a little different from the outside, but they fit perfectly and install perfectly. I could not tell the difference in print quality between the manufacturer's original toner and this toner when comparing the first half of my print job (which was printed before the manufacturer's toner ran out) to the second half of the same print job. (which was printed with this replacement toner). I hope the other cartridges in the pack work just as well, I have no reason to think they won't. for insufficient packaging. Fortunately, the cartridges inside were each wrapped in their own bubble wrap, and that was the only thing that saved them.
