I bought one of these cartridges straight from Amazon. It was listed as new but is in fact a refurbished item. I suppose this is common among toner cartridges since they get recycled. This one causes my printer to display "Toner Low". Also, it leaks toner so my printer is now a mess inside. I have never had this happen with a name brand cartridge. I give it one star for actually printing. I have emailed Radian support about the false error message and have not gotten a reply in more than a week. Save your money and buy another brand.Later: the cartridge caused my printer to stop working. I can't be sure but it appears that a plastic piece fell off into the works. Stay away from this disaster. Amazon is giving me a refund after I return it.
