Good cheaper Toner for HL2030

First of all, I can not say anything negative about the toner. The printed image is indistinguishable from the original Brother cartridge with a. In use, the toner is in a HL2030.
However, there is still something you should know:
The drum of the printer holds allegedly 12000 pages. For me, the printer has reported after about 5000Seiten the new drum would be due and has refused to resume printing.
In the printer's manual was that the term of the drum would be greatly reduced by a third party vendor to use a toner. But I do not buy a new, expensive sau, drum unit. So I took the drum unit, cleaned with compressed air and reinstalled. Behold, it prints on.
