Thanks Chanel !
Did you use it with PT2 heads as well ? Thoughts please if yes. I assume that's a picture of the RTA section. How did that work for you ? Could you get a satisfying MTL vape from that at 10-15 watts ?
I'll give you my thoughts.
After giving the STM high praise (a few posts back) for it's ability to use the PT2 heads, I now have to say that I'm not impressed (with that aspect only). The vape is fine. Very, very good as a matter of fact. The problem is that after vaping for a while, it starts to gurgle due to juice getting in the base. I believe it's getting in through the chimney (but I'm not sure).
I've tried pushing the top cap up to the STM top tube, and even put a small o-ring on as well. Still starts to gurgle after a while. Set it down for several minutes, pick it up and vape and it's fine, for a few minutes.
I got so tired of it that I finally broke out the rebuildable head, swapped out the coil it came with (.5 ohm I think) for one of mine, and am happily vaping away with a 1.9 ohm coil at 7 watts with nary a gurgle.

This thing is so much more efficient than the PT2 that I don't dare increase the wattage until I mix some lower mg juice. Even at 7 watts, it's hitting WAY better than the PT2 ever did.
I'm still going to fiddle with using the PT2 coils at some point. Maybe some silicone tubing stretched over the STM top tube that would still allow the PT2 chimney to fit into it. It's worth a shot.
