You will not regret it. be sure to get some Smoktech 1.5ohm dual coil cartomizer (s) with it and get a trustfire if you don't have one.
I hated the duels since the LT nor the KSD VV did not power them enough to get them to perform proper. Now I am in love with them. I am even using the smoketech tank again after spilling 3mls on myself

I found with the other devices I would always just suck juice into my mouth and never got enugh vapor.
I know that I clicked the "email me when you have stock option" and got the email. I think it was a system meltdown from all you guys making so many darn orders!
hahah like I don't) i'm averaging one a week lol.
