The SUB-HERB bubbler is not just some bubbler. It took 8 months of study and sourcing of the artizan glassworks along with best quality. It hold water , cools your hits and makes you very happy. This Is just a badass glass piece. This bubbler works like a dream. No water loss any direction.

Pretty simple to use, pour water in the mouth end of the bubbler and let the bubbler leak any excess out of the bottom. Take a paper towel and dry out the bottom of the bubbler (part that fits onto the tank) if any does leak out due to overfilling .  Use only the ceramic base of the SubOhm Herb tank , add your leaf or concentrate and attach to your battery . The bubbler slides over the red o-ring for a tight seal 
 A Good Start setting for a strong vape is between 24-29 watts.  Mig Vapor warns against using it over 30 watts as it can burn up the ceramic on the part that you load the herb into
