Charlz are the small wicks giving you trouble when the juice level gets below them?
No. It tapers at the top and has little room between the post and shell. So when you tip it to vape it, it get's enough on the wicks. I'm also vaping in my Kuwako which automatically means the iturbo is parallel to the ground when I vape it. I find I tend to try to tip it up more as it gets down under .5ml. That's when I refill it anyway. I'm vaping it down now and it does get a little drier towards the end. I like the short wicks now. I think the long wicks trap a lot of juice. Can't fight gravity.
