well if that's the case I'm OK with that. I have had really good luck with cleaning the CE2/CE2XL and not having them leak.
But the clear CE2s have a silicone seal at the base which does help some. From the pics of the Vortex, I can't see any evidence of a seal. The beauty of the CE2s is that with a minimal amount of modding, using a syringe tube, they can be cleaned and reused many times with no issues. The syringe tubes don't crack, they will start fitting a little loose after a while so you either flip it or cut another one. Unless you screw up the wicks, ruin the seal or burn up the coil, they just keep on vaping.
I understand that manufacturers and vendors don't necessarily like things that last a long time. And I know the GV guys are really making an effort to put things out there that work well for us and I commend them on all their work. I like the longevity of the CE2s cuz I can't just walk into the local gas station and pick up cartos. I just got my last order of fluxos and I still have 3 unopened ones from my previous order of 10 that I got 2 months ago and 6 of the seven I'm using still work. The only one that doesn't work is one that I screwed up the wick on. Now I use that one for sizing my tanks to ensure proper fit.
I will probably order some Vortex to see for myself how they work, see if the can be modded or adapted to a tank...I just can't seem to leave things alone.
