I tootle puff with a STM (AFC almost closed) using a 1.8 ohm coil. Last week I received a few spare rba's that I had ordered from FT and decided, on a whim, to dip my toe in to the sub ohm pool.
The STM comes pre-loaded with a .5 ohm coil and I thought, why not give it a try. Got it wicked, installed in a tank, opened wide the AFC and took a DL hit. Forgetting of course that when I switched from the PT2 to the STM I needed to reduce my nicotine % by less than half due to the increased efficiency.
Quickly modified my draws.
The clouds were nice. The buzz was little surprising and the insomnia that night was unsettling.
OK, I tried it. Now back to my tootle.
