Tube RTA. I think the listing is gone.
Compatible with kayfun\orchid\silverplay accessories.
The coil in the photo is my all-time favorite also, single or dual, set to work unregulated or regulated. 28\32g Clapton with 3 wraps for a whopping 0.8Ω(or 0.4 dual). First few puffs snap crackle and pop and disappear once the liquid is warm. I believe the tube has a 2.5mm airflow but I could be wrong, maybe 2mm. No longer have the Atto "mech" pictured as the 3 chips I had always putout 0.2 less voltage than the battery... It'd put out 3.5v when it's 3.7 and then cutoff "dead".

Knock knock, let the devil in.
Malevolent as I've ever been, head is spinnin'.
This medicine's screamin', "L-l-l-let us in!"
