Buying a Brother TN 2000 Compatible toner nine early May 2012. Nothing to say at the beginning: flawless. But I confirm to other users (see comments) toner that is not due to the length: little used (about 200 printed pages of text), it is already almost empty (December 2012), and I have to regularly go out for distribute the product to avoid white stripes aside. This is a rip off!
