i bave a cleito on my rx200 and it has a .4 ohm coil in it and it sucks through juice. I just picked up a xcube 2 with a tfv4 is this thing going to suck through as much juice you think? I had a tfv4 when I had my ipv d2 mini and I had nothing but problems with it, it leaked, sucked through juice. I liked it minus those things.
