So I got a tugboat clone and an iStick 20w and I built the rda and too find out, when I put the tugboat on the iStick it doesn't even recognize that it's on there. The iStick doesn't have an adjustable pin and neither does the tugboat clone. (I don't think). And I put my aspire nautilus mini tank on the iStick and works like a charm, I just don't understand it. Anyone that posts, thanks in advance.
