Personal experience on the DR, I had the RTA before the
rda. I thought the RTA was pretty good with the airflow configuration it has albeit a little more cloud than I usually prefer. When I got the
rda I figured it had to be even better, right? That's usually how it is. The RDA is exactly the same vape as the RTA. That made me a little disappointed because I was hoping for more, not the same, as otherwise I would just have stuck with what I already had.
I'm not knocking the concept, I think it's good, but maybe I had unrealistic expectations. I also hate those long wicks. I've not had a dry hit in either the RTA/RDA but I think I subconsciously give it a little longer between draws to allow capillary action to pull the
juice up, certainly in the RTA.
I got an Iconic on clearance for $10 From MyVpro. I like the idea of bottom air, and it's got a pretty deep well so no leaks to date. It's a massive cloud chucker. I could fog a decent size room up in no time. It's just not my style. I may add another little flavor banger to my FT order.
