I love the design and look of the PT2, but as mentioned previously, they just don't perform well with 100% VG (which is my current ADV is). I've tried everything. Removing flavor wicks, rebuilding the heads, modifying the top cover thingy. It works, but the flavor is very inconsistent.
What I really like is that you can change the heads out without emptying the tank with minimal fuss. I can change the heads on the vivi nova's only if the tank is at least half empty, and that's not pretty.
I've got some SS mesh on the way, I'm going to try that. I really want these tanks to work with my favorite juice.
Oh, and you can get replacement tanks at gotvapes for a very reasonable price.
