I love my Billow tank!!

This
is my 1st RTA, but I've been very impressed.. Gonna get the Nano kit because I usually don't fill it full. It performs pretty much on par with my drippers, huge thick clouds and great flavor! I bought 2 new drippers when I got the Billow, and have pretty much retired all my RDA's now.
I did have a slight leaking problem, especially if I accidentally left it tilted; a bunch of juice would start flowing out the airholes.
But I've noticed that this tank seams to work better with
RAYON, compared to Japanese Cotton Pads..I've noticed that even the tiny juice seep from the AFC
Screws has pretty much stopped when using rayon (plumbers tape installed also), and it doesn't leak when I leave it tilted now!
I've had the same coils on this tank since about early December and vape about 3mL a day out of it.. I usually run it @
27.5 Watts: 0.4ohm, dual 26g Microcoils (5/64in).

I love this thing. Some of the best money I've spent on vaping and it was only $30!
