Innovera DR890 Drum Unit for HL-L6900DW, Black

This advertised as being a Brother drum so I purchased 5 drums. All 5 were used up in the same time that one drum lasts. It made a complete mess with all of the black dust in and out of the printer. The last one I put in, I was surprised that I already was out. I thought I would order more drums in a week since this was the last one. This drum was the worst as it only lasted 5 days before it had black smears on my papers. I had to reprint a 180 document and pick the best ones to use. Sometimes printing 3 or 4 times on individual pages. I use a page separator and it ruined those pages with black smears as well. I wasted a lot of money and paper on this. If it is advertised as a Brother drum and price seems too good to be true, do not trust it. I have always bought off brand drum in the past, and they worked way better and lasted 5x as long as this.
