thanks guys! i actually had a glass head one that was pretty much the same thing but a little taller. it was glass on glass but had a rubber stopper so u couldnt take the diffuser out. a week ago it got stolen at a party so i got this guy. this bong was 280 then i paid 60 for the ash catcher and its by far the smoothest hit iv ever gotten from a bong. only complaint i have is it takes me about an hour to clean it
