I was never a fan of the T3. I used the Smokeless Image version and never liked it. Always a leaker. This has pretty much kept me away from any other Kanger bc. But I am really tired of the miserable battery life I am getting from dual coil. So I am thinking about trying the single coil bc Kangers. Either the PT2 or the EVOD. Are these plagued with leaks like the T3 heads??? I now some people love the T3. But I know from reading that I am far from the only person that hated them and had miserable luck with them.
