I think you misunderstood.. nobody's saying to get rid of the 510 (though arguably it's an outdated threading from a time back when only cartos were around, & have a fundamental flaw when used in conjunction with today's larger/heavier toppers)...
I have a $50 Chinese-made mod which accepts all my tanks, and also includes a removable ring for even more access & compatibility.. My ProVari? I need a 510-to-510 adapter to fit two, and a third which needs to be loosened so it can get enough airflow... all 3 toppers came out in the past year or more
Sort of expect a little more from a $150-$215 PV in that department.. I understand things can change fast, but an update is long overdue at this point to keep up with an ever-advancing industry
I appreciate ProVape wanting to make sure everything's good before any launch, and I'm sure a version 3 will be a welcome change, hopefully knocking the socks off both existing & potential ProVari owners...
And would I get another V2.5, despite my biggest/only real gripe? In a heartbeat.. But I'm going to try to hold off for the inevitable V3...
P.S. Keep the crop circles!
