After spending some time with the Hunibadger, I really like it.
I did not add a bubbler to keep it portable as possible. Portable it is. With the mouthpiece stored, the unit is about 5" long by 2.5" by 1" complete and fully metal, feels solid as a rock. The end cap that holds the mouthpiece and protects the tip also holds a small glass (.5g?) container of extract. I have not tried to count the number of one minute heating cycles I get from a charge, but no complaints about battery life at all. I prefer the low temp tip, flavor is far better, so that likely helps. With 18650s and replacement tips as the only consumables, this should last a long time. Cleaning is simple enough, wipe the tip with an iso pad and run a pipe cleaner through the unit once in a while. Technique is important though. Better to lightly tap into the product from an edge, you don't want a huge glob as it will take a long time to vaporize, losing flavor and making a mess the whole way. It is very efficient consuming your product this way.
It really check all the boxes that I was looking for. The only problem is you look like a crack head using it, so not in public.
