Sorry for mentioning another venders item... Please delete if not ok.
I have a drip on demand kit i bought a LONG time go from another vender, but could never gt it to work right. I had an ah ha moment after screwing up a top seal on one of my BC pretty much ruining it. Decided to try and cut the tube down to about a 1/2 inch and take the air tube off and mount the drip on demand on the tube. This thing works awesome! I get the good flavor the BC puts out and a 5ml bottle, vape is a bit cool though... I do have to squonk it a bit, but its easy to tell when its running dry cause of the see through tube.
