There's a few
reviews on YouTube that look pretty good. For the money it seems pretty hard to beat. I have an Atlantis myself and have been really pleased with it but have also considered the
smok VCT. Whether or not it will fire on an istick depends on which one you've got. The original 20 watt unfortunately only fires down to 1ohm. The new 30watt or 50watt would both work fine and fire that without a problem. There's a couple threads in the cleoromizer forum about the VCT you may want to check out as well. Here you go..
