Its been what 4 days now and I am rocking my Reo. Its really a sweet device that delivers great vapor & hits, great flavor, and it looks great too. What else can one want? I found out I don't really need that much variability in voltage as the flavor tends to shine in the lower range (for me). The Reo was also very easy to adapt to. Its easy to use right out of the box. Squonking is very simple and it works amazingly well. I swapped bottles last night and I thought it might be problematic mixing juices and all. What I found is that a little of the original flavor stays inside the tube and so for a short while I continued to vape that flavor but after a bit the new flavor kicked in and that was that! No issue there. I just wonder how often I have to apply that naoloxone stuff to the firing pin.
