I've had the v2 for a couple days and haven't run into any problems yet. First build I used Rayon and was in a hurry. I just cut it flush with the deck, trimmed a little and screwed on the chamber. That pushes the wicks down naturally. Vaped 2 tanks with no dry hits and no flooding.
I rewicked with Japanese cotton. This time I cut even with the edge of the deck, then cut the tails into points. I just let the tip of the wick into the
juice channels. It works outstanding. Less wick is the key.
