At first I was skeptical, given the no-name goods, because I'm actually a friend of original parts. For the price (19,90 Prime) I am, however, become weak. The risk is indeed low, because if there are problems, there is a guarantee and we will send the part back easily. Until now, however, there were no problems. The drum was delivered on time and packed neatly from Logic Seek / amazon. I unpacked it, used the old toner and installed it. As some reviewers had problems with the automatic duplex printing, and we use this feature often, I have the same a few pages duplex printing and everything worked beautifully. The printed image is again super. Until now I could not tell the difference from the original. I wonder why you should spend up to 133 for a genuine Brother drum if you can get a comparable part for 19.90. Am curious how long my part will give pleasure (date I have written up again.) And will report if there are problems. (As long as you read nothing else here, everything is going well.)
By the way: After inserting the new drum blinked still the Drum LED. Have the network a quick guide found, how to reset the display: printer is turned on. Front flap (ie large, over which one also changes the toner) open, Go button and hold until all the LEDs light from top to bottom, close front cover again, ready.
So far, just buy it!
