Been using this baby for years - in fact it was responsible for me finally giving up the evil weed (tobacco) about 5 years ago! The smoke you get is super smooth, allowing for a fuller pull, less coughing and a general all round sense of well being as you put it down, lay back and float away... or jump up and get on with things in that energy giving way only a good, pure bong can give!
I can honestly say I've never smoked a better bong - big enough to give a fully cooled smoke but not so big the smoke gets old before it reaches your lungs.
Just remember to put it on a shelf when you've finished or you'll be buying one every year like I do!!
