Funny thing is there seems to be a number of people who don’t believe this actually works and as an asthmatic I am constantly looking for ways to make my habit easier on my lungs. The bubbler has an immediate affect on the vapor and the hit it so smooth it almost feels as if nothing is being inhaled. Also the bag does condensate quite a bit and is to be expected but my bags are bone dry after letting the bag dry overnight. The wet bag thing is truly a non issue. Also I’ve used my volcano bag with my solid valve on my bongs and although the experience is smoother it’s definitely not the same as with this bubbler. I think it’s worth every penny.
