Sometimes you need to get serious about your smoking up. Maybe your bong just isn't good enough at making the water interact with the smoke. If you are an experienced smoker but still keep coughing up when you smoke, the problem isn't with you, it is with the bong itself. That's why we are glad products like this 4 arms diffuser ash catchers exist. It significantly increases the comfort level of a smoke, and makes sure that you get the best smoking experience possible. It also looks really, really cool ' we love the barebones aesthetic this thing has going on.
