I got two rainbows and one more SS. I have 2 more en route from FT (tracking indicates "acceptance" in China - I'm guessing at least another week before getting anywhere close to me.) I wanted the HCigar, but when I tried ordering, it indicated out of stock. Went with the other kind.
I'm LOVING my Subtank Mini with a 1.6Ω PT2 head on my Nemmy right now. Looks sleek, and hits quite well. I put a vape band around the locking ring, and now it's quite easy to spin it to lock/unlock
I believe these use dual coil heads. I'm not "amused" by those. I *think* the chimney is a touch higher than a PT2, to give room for the 2nd coil configuration. I also *think* that if you want to use the single-coil PT2 heads, you probably need a 2nd grommet (flipped upside down) to prevent/minimize leaking.
