This compatible cartridge is not as good as the Samsung name bland. I replace my genuine Samsung cartridge couple of weeks ago. My printed pages have smudgy edges . There is also some black powder leak at the beginning. Back of the pages are covered with black powder toner and they got onto my desk because I did not notice it at first. I took the cartridge out and shook it a bit and cleaned the casing. This helped but printed pages still has smudgy edges (on one side). I do not recommend this product. Very disappointed. I wish that it will run out soon so I can replace it!
