It's the the Optimus S rda. It's stainless steel, has adjustable airflow, and it quite small. It's really not much bigger than a typical pre-built dripper. The bottom cap is fairly loose but I've never had it leak on me. Overall it's a great RDA, especially for the price.
If you feel like it, try the same setup but on a 1/16" bit. I find it works better that way.
I have! I didn't really notice a different though
EDIT: Re-did a 1/16th, 14 wraps, came out to 1.6Ω. Very satisfying! I was looking lately how to step things up a bit but was being stubborn about my current builds as they worked so well. I might have to try hitting 1.3Ω next coil. Hmm.... I wonder if a month or two from now I'll be building nano coils just to get that next "bump up" in satisfaction.
RYEDAN, WHAT HAVE YOU DONE!?!?!
