I got my reo and have been using it the last few days... It's great, built like a tank and it works exactly as described, however flavor doesn't seem to be quite as good as straight dripping. Maybe it's all in my head though since it's basically the same thing. Maybe it's the atty? Using a brand new Joye LR 510. Going to get some empiremods atty's and see how they do on it.
I realize this is a dripping thread, but my girlfriend uses the little 808 batteries and she recently got a Kanger T4 clearomizer for it. I have HATED every clearo I have tried, but this one surprised me. Flavor and vapor production are excellent. Certainly far superior to cartos and not much bigger in size. Easy to fill and so far zero leaks. Handled MOV Sunday Morning with no problem.
I too have noticed the slight decrease in flavor between dripping and bottom feeding on my HH.357s and Cisco LR atties. Rebuildables are better on a REO, but that's a topic for another thread.
Dripping to me is what smoking a pipe was when I used to smoke mainly cigarettes. When I get home after a very good (or extra stressful) day, I pop my 2 ohm HH.357 long barrel on my Provari at 4.3V, 3 drops of whatever juice I feel like having (if atty is new or recently cleaned I prime with exactly 10 drops), and savor the unparalleled, full flavored billowing clouds of vapor.
On the go, it's arguably the least practical way to vape. But used as I described, little to nothing is as good as dripping on an HH.357, in my opinion.
