The only down side that I see to these T3's is that there is the potential for the seal to restrict the wicks if over tightened and especially if someone is using a thicker juice.
That is why I added a o-ring with my 60/40 PG/VG juice.
I have noticed that if it's on the verge of flooding, I can snug it up tighter and the opposite is true if it's on the verge of giving a somewhat dry hit or a harsher TH. I can back it off a tad and this seems to allow the wicks to wick better.
The o-ring keeps the shell snug and it doesn't rotate freely.
It also give me the ability to control juice flow.

Got 2x of these today and me and the wife love them so far. I replaced a vivi nova mini with it.... It is really easy to draw, no leaking, seems really sturdy, great flavor.
my nova mini has started to darken the liquid after 1/2 a tank making it taste like crap (i have 3x heads I rotate/clean daily and all are less than a week old).
