I've tried many non-OEM toners over the years and none of them produced print quality anywhere near that of genuine HP toners. Until now. When I bought Uniwork toner for my Laserjet m203dw I expected another disappointment. But to my surprise, the printouts were consistently good and indistinguishable from the originals. It remains to be seen if it will deliver the claimed performance. And even if you don't, the price difference alone can be worth it. I will buy more of these.
