Some of the reviews that I read were negative but I carefully followed the Brother directions for installing new drum units and did not encounter any problems. The drum unit has been performing just as well as the original drum unit. I think the negative comments were from people who did not follow the Brother instructions or have other issues with their printers. We used to throw away our printers when the drum unit was no longer working correctly because a new Brother drum unit costs almost the same as a new printer especially if the printer is on sale which they are fairly often if you look around. We felt guilty about throwing away otherwise perfectly good printers but we will be stocking up on more of these drum units so that we can get a longer life from our printers and keep trash out of the landfills.
- How accurate was the sizing? The drum unit fit the Brother unit as specified.
- Please tell us about the quality of the product. I have not been able to tell any differences between this drum unit and the original Brother drum unit that came with the printer.
- Was the product free of any manufacturer defects? I did not find any manufacturing defects.
