I've got two of these, using the velocity style decks, and haven't had a leak yet. Using rayon, I trimmed off ~80-90% of the wick and have it just barely touching the deck right around the
juice port, making sure the hole is clear. Using one with 26ga Ti dual coil and one with 28ga SS430 twisted dual coils - both are absolutely stellar vapes, 50w on the Ti and 45w on the SS430. The Billow v2, Goliath v2's, Cthulhu v2, Crown, and Subtanks are all on the sideline taking a break.
Using the 2 hole vape band, blocking the holes that aim at the posts. On the one with Ti, initially I'd left too much wick in the tails and it was a bit muted on the flavor. After trimming the wick back further, it really came to life. Been using that first coil since (~70-80ml) and last night built the second with the SS, wicked the same, and instantly it was a perfect vape. The flavor has been as good if not better than any of the other tanks along with ample vapor production.
While I've not been a big RDA user, mainly due to not liking the repetitive dripping aspect, I have dabbled here and there and this aromamizer definitely reminds me of that RDA hit. However, there are a few subjective negatives - it can whistle a bit, especially without the vape band off. I don't much care for the vape band myself and I'll probably do like some others have done in this thread and go with another solution as the band will accumulate condensation over time. While mine hasn't leaked, I've not tested it over a 45 degree extended lean. I've caught myself leaning it against my leg while sitting in the chair but haven't had a drop come out. I think if it was laying fully on it's side, the condensation that builds in the deck area could lead to a few drips.
