Quoted from CrazyLevi:Shooter knob mods are one of the biggest headscratchers in an already often batshit crazy subset of the hobby.
Casting aside the aesthetics of it, which are truly in the eye of the beholder (though lets face it they all look hideous), they are HORRIBLE for the gameplay experience, big, heavy, clumsy misshapen messes that really make every plunge an awkward misery. Not to mention I can only imagine the swamp of bacteria, dead skin, and general filth that invades every crevice of these sex toys on a spring.
Stop the madness!
I can safely say without sarcasm or hyperbole, this is the greatest thing ever written.
