This is why I like to see other people's thoughts on things and other people's reveiews. I did find it a bit tight to wick with a 3mm coil. Maybe I just used too much cotton wicking the 3mm. I got a good draw but when I took the deck out to have a look some of the cotton was still dry, and that was with putting about 1ml though it as well. I didn't just have a look after a couple of draws. I rewicked a couple of times and tried it without combing again on one of them and got the dry cotton again so just combed the other times. I found with a 2.5mm coil you can just fire the cotton in willy nilly and it wicks perfectly. Such a forgiving tank with no real faff at all.
I did notice there's a tiny gap at the bottom of one of the posts but it doesn't affect the tank at all. I just assume it was the way it was designed.
