Every time you decide to spend a lot less on an "unbranded" name, you fear you're wasting money and time. Not with this drum. It fit perfectly, worked as expected and was less than a quarter the price of a well known brand. I took a chance by reading the reviews and found that others who praised this drum were right. You'll do your research, sure, but this is one of those products that comes out of the box and fits like it should. What else do you need? I have two printers that need a TN660 drum replacement and I will be going with this brand. I'll update this rating for durability once I've used it a bit. More than.
