I've heard innokin Disrupter is hot in USA? Do you want to try

They carry these in a smoke shop down the road from my girlfriends place. They're expensive as hell and I can't see it as very portable. I use the Vamo V2 and even that is a bit bulky for me. SO for the most part, I just keep a couple E-Go button batteries on hand and use a generic claramizer with a 2.1 Ohm coil. Much cheaper, easier to get supplies and easy to carry.
