I have bought tn760 toner which gives 3000 prints but after 392 prints toner low and after 416 toner gone . That number is not even close to 3000. After that I called brother customer service , they are not helpful and even I am chatting they disconnect in between chat . Very bad . And surprised by 416 prints with high yield toner. User's recommendation: Plz make sure before you buy product of brother.
