I bought a protank 2 a couple of weeks ago...well it worked great at first but after a few days its started leaking out of the bottom coil into my battery....I'd clean it up, completely disassembling it and putting it back together, it worked for a few hours then the same situation occurred. I even googled and watched youtube videos on this issue and none of the recommendations remedied this issue. Thinking maybe I got a bad egg I purchased another one on friday (when it works it works great!.) Well low and behold the same problems started happening; except the new one also accumulates liquid underneath the drip tip! Im fed up with this crap and dont want to give kangertech any more of my money, so I'm asking some more seasoned folks for a recommendation on what would work better tank wise, its been very frustrating! Thanks ya'll!
