Pros: right length for my DC40 vacuum bulb, same size as my original brush. Cons: Screws not included. The brushes are the wrong size. Too short. So I unscrewed the old brush plate and used that instead. But since the common brush and screw are already old, I have to break the old plate to unscrew the old brush. And I don't have exactly the same size screws, so unfortunately I have to use whatever I have at home until I can find them in the store. And the other side plate is new from this Amazon seller, as you see in the picture, I can't screw the other side hole because it's too short.
