I just got a Vaporite Mini Digit and I am totally confused as to how to use it I get that you plug it in and let it heat up while you load the chamber in the whip, but then what? Once it reaches the temp, do I stick the loaded whip on there and just leave it after I've hit it, or do I have to take it off in between hits? What is the optimal temp for vaping? This is a little different than my MFLB.
