I just wanna know if they make it that much more cooler they dont look very good but still its an extra chamber im talking about the ones like this http://gorillaglass.com/images/ASH-6.JPG
the amount that an ac will smooth/cool the hit depends more on the size, and amount of water above the downstem, as well as if its diffused or not also, with a larger diameter downstem there will be less drag. and with a taller a/c there will be less spill over into the bong. a larger a/c will also take longer to get real dirty, where as something real small like that will get dirty quick so that a/c will do what its supposed to do, give additional filtering and cooling, and trap most of the ash before getting to the bong but, its so small your probably going to have a few problems. it will have a lot of drag because of the small diameter downstem, it will spill over into the main bong like i mentioned, get dirty real fast, and not filter the smoke as well as something with a larger diffused downstem the main problem i see with that ac is there is no carb hole, and since its a 1-piece you cant pull the bowl. this will leave the ac full of stale smoke every single hit you take. id suggest shopping around more, that ac just has too much going against it
