I've been using this tank for a week now and can't believe this thread doesn't have more traffic.
The Serpent is the first single coil RTA I've owned since the Kayfuns. Matter of fact, the Serpent reminds me of a Kayfun on steroids!!
What I like the most about the serpent is it's versatility. I have 4 Vaporshark DNA 40's and besides being used as paperweights or with Subtank Minis, don't get much use. With the Serpent, I can use a .5ohm coil and vape at 35 watts and it's a great vape!! You can also put a big fat Clapton in it and crank up the power for yet another great vape! Love the versatility!!
Major....I initially had leaking while filling issues as well. Don't know why with juice flow control but I did?? What I've been doing is turning the tank upside down then opening the juice flow and, don't know why, it's not been leaking??
I thought that single .5 coil at 35 watts would save on juice but that is not the case! This little guy goes through the juice pretty fast which only means this tank works very, very good!!!
