Well, you may be right. The guy who is posting (Minion2) is a madvapes employee (it says supplier associate under his avatar) so I'm thinking he knows what he's talking about... but I haven't had one in my hands so I can't claim to know anything more than what I've read.
I decided to wait and see. I can't assess the value of a nicely priced tank if the cartos are different than regular ones and not available with a price tag yet. But if the flange is removable and transferable from carto to carto, that would be nice.
EDIT: Well, I'm looking at the pictures and I have a carto in my hands. I don't see what you see, I guess. I can't figure a way that the flange could be separate from the carto.
Anything between where the threads stop at the top and the barrel of the carto would both block the air holes and make it so the carto couldn't thread all the way on a PV and make proper contact. And, if the carto screws in to the flange assembly, then the outside threads would be on the flange assembly and would therefore be larger than the inside threads (the cartos threads) - so that would no longer fit 510.
Six I dont have one of these but if that flange is only like 1/64, 1/32 or anything less then the space in between the bottom of the carto and the space before where the holes start it will be ok, that flange is so thin and threads onto 510 threads of a DC Carto it would work on any carto, There is a 1/8 space from the bottom of the carto tube to where the air holes start, and this is where I am thinking this thin flange sits. I dont have one of these yet and I saw the guy is a supplier assoc, so time will tell, I am going to email mad vapes and see what Hoggie says
Edit; looking at the picture a bit closer it looks to me like that thin metal flange on the bottom of the carto is "let in " to the bottom grommet Six, just for added leak protection, I still think a regular Smoktech DC Carto should work and not leak since they are all a 9mm tube, I also heard it has a tripple O-Ring in the bottom ( dont know if that is true or not ) but even if it had a single O-Ring of the proper size it shouldn't leak. I do like the way the flange is "let in" to help prevent leaking though, but I dont think it will leak without it, other tanks dont leak and dont have this. Added protection is a good thing though and I like the idea either way. Time will tell as people get them, I'm waiting on an email I sent to madvapes to get the answers, will post when I get them or maybe Hogie will post before hand to clear this up for us.
