He said that it doesn't leak. He said it is a richer vape. He pointed out where you have to be careful as you build and install it - the lining up of the pin in the base to guarantee effective air flow, which was not present in the v1. He did a full build which, if you know the v1, you can see exactly how it is different.
Not sure what is missing in terms of comparison.
Edit: That last line doesn't quite read as I meant it to read. I (and others) will likely be overloading this thread with comparisons soon enough, so if you ask questions about the v1 vs. v2, they will surely be addressed in due course.
First of all I've ordered the Diver V2 on the first day only because i trust Atmistique.
Regarding the review of Todd in my opinion he said nothing of new

Atmistique already said that the Diver V2 was built with the Idea to improve the taste and avoid any leak.
What you seen?
Have you seen the Diver V2 inside a tank? I haven't seen it, I have seen a Diver V2 used with the billet box.
IHMO was not a review, he didn't compared the two atomizer side by side.
Yes, now the Diver V2 can be used also in the billet box, but again, we are used to vape it inside a tank, so a nice review would have been put both V1 and V2 and explain the difference.
Anyway as I said this is only my personal opinion.
I should get it in the next day ( hopefully tomorrow ) and so i will see how perform.
