    Rated 3 out of 5 by from big brake master cylinder I have not bleed this product yet so I cannot give it a complete review. But I will say that the powder coating is not show quality, it has runs in the lid and the finish is very rough. Yes the price is reasonable but not for the show person.

    Rated 2 out of 5 by from Poor black finish Pay the extra for a chrome one. Brake fluid takes off the black coating.
