My current set-up after 3 months of vaping.
I have included my not so savvy remarks.
left to right:
Vamo with a BT801 - The 801 is a good RBA, right behind the Phoenix in all categories.
Ego VV battery with a Phoenix RBA - the Phoenix is a great RBA, best of the lot for vapor production, good taste, consistency and rebuildability. Will hit like a train if you crank it up.
Ego 650 battery with a boge carto - Boge are the best in their class by far IMHO.
Homemade device with an old titan tank atomizer for tasting.
I made this out of a ear/nose hair trimmer from harbor freight. It didn't work very well except for anything except scaring the cat, so I made a mod out of it ;-) It has a 14500 battery.
(It really was a fantastic cat chaser, I kinda miss that.)
EVOD on a 650 Ego battery - I started out loving the EVOD, then it just started having problems, gurgles, leaks, poor vapor. Too bad because it was a good vape.
Vision Eternity on another 650 (650s are a good little battery) - The Eternity is a good RBA but I rate it lower than my other RBAs.
Homemade nicostick/puck mod with another taster atty, it uses 3 AA rechargeable batteries
18650 Ego upgrade battery with a Mini Vivi Nova. My current favorite, good hit, good vapor, great taste, very consistent and trouble free.
I don't know if this is common, I haven't really seen it addressed on the forum. But I will usually have 2, 3, or 4 devices on my desk or carrying with me and hit em at random. I think the different flavors are more intense this way.
