    Noticeable Improvement

    I can totally tell the difference between this and the standard six-slit diffused downstems. It's better for sure. Not night and day better, but a noticeable improvement that makes me wish there was a law banning the manufacture and sale of non diffused downstems and basic slit diffused downstems.
