Ours is used exclusively with a bong. And have been using it that way for over a year now. I love this vape! I've had friends try the bong, they laughed until they started coughing their lungs out from the huge cloud of vapor they inhaled lol! I'll bet I helped sell at least 5 of these.
I've been using my earlier model Herbalaire for probably 8 years. I bought a back up and it's collecting lots of dust. I don't use the whip, I bought 5/8" surgical/food tubing (cut about 3" length) and put that directly on the mouth piece. I get better, stronger hits.
