This is the dumbest thing ever. I love Aspire tanks. Compatibility is one of my favorite features, as there are tons of other companies' coils that will fit in an Atlantis, or a Triton, or a Triton 2, etc. My Triton is one of my old faves, and I just got a Triton 2 today, incidentally it was free so there's really nothing to complain about at all. But this has got me totally befuddled! The 2 has LESS features! -No top airflow is by far the most glaring error, and it shows. This thing does not pull nearly as freely as the 1. -The top fill ring is much harder to turn and properly "click" into place. It's like a pickle jar that never fully opens. -The body is just simple pyrex glass, instead of the rather clever metal "cage" that protects the 1. Again, ain't gonna complain about free stuff. But what was Aspire thinking? There's gotta be SOMETHING better about it. Right?
