Ya, on my siren V1 the capture system is much better than most tanks I have used. But I see they changed it for the V2, works more like a dripper from what I can see. However wicking the V1 is a complete nightmare for me. Not enough wick and it gurgles and leaks, too much wick and it doesn't wick worth a darn. IF you get it just right it works pretty good. I still find myself having to re wick it every time I fill the tank if I want it to perform really well. The wicks are just too thick and too long for how I vape. I tend to like dark, sweet juices so the wicking gets gummed up pretty fast. This is one of the few tanks I have used that I am thinking of just cleaning it up and putting it back in the box.
