These toners, 1/3 the price of the Samsung original toners, perform very well, last a long time, and make perfect sense for a grad school student like myself. I write academic papers, teach a class, a print a LOT of materials, and these toners don't let me down. I get quality prints, and the toners print clean and clear down to the empty cartridge. You can not go wrong, so try one for yourself!
