so far after 2 days of heavy testing unmodded, heres my only complaint, when it gets half way maybe even more empty, at times i get the dry taste, which goes away after the wick gets soaked i guess, i take it that since its the wick laying in the tanks there is no way of getting juice to the wick if most of it is exposed while being vaped as juice lays flat. but it hasnt been anything major or probmatic like older revisions. mine dont have the afl so maybe that helps in that regard.
other then that one thing i dont have anything to ..... about, the connectors are perfect, no dents, no leaking at all, and it wicks well and the ohms are what they should be.
Now i will ptb one to see if it does any better when the e2 is getting low on juice.
