Vapor concierge
@lwien I like what @Tweak said comparing the two bubblers. I just used my D020 last night with the Air and really enjoyed it. It required no priming (that's what I call when I hit the can until vapor starts forming and then exhale before starting again with a full can of vapor). I prime whenever I use the 187. Both good choices and I'm glad I have both as they will both get used!
