With a diffuser the smoke is softer and also it has a cooling effect. The holes at the underpart of the Roor diffuser plug, the diffusor, divide the smoke in many little bubbles, so that the smoke gets a bigger surface. This Roor diffuser plug does not only connect your 14/5er bong with a 14/5er downtube, moreover it gets you a better smoke experience.
