Whats up everyone!!! So I have been using Ego Twists for quite sometime now I suppose. Well I decided to try out the ole 801 Fusion Cartomizers from Ikenvape and I love them! They do seem to always be steller performance. Well I obviously got their "Stealth" 510/801 Adapter and it pushed the center post down on two of my batteries because its just a little long. Well I pulled the posts on both with a small screwdriver and the little orings both fell out and I lost BOTH of them!! lol. So now the center post just flops around and an interesting thing is that on Carto tanks and Vivi Novas they still work fine. But when I try and use an 801 fusion with that adapter in a tank, it WILL NOT FIRE. If I angle it just right and its still far from being screwed all the way down sometimes it will fire intermittently but its so lose the tank and carto rattles around side to side, back and fourth etc. So unforutunately I need to get a better adapter or just stop using them and go back to 510 as I never had a problem with center posts on anything until this so i'm not impressed that those two no longer fire the 801 adapter. But glad they still fire everything else. I also find myself having to constantly screw with the posts on those two batteries now. Bummer!! So I'm hoping I can go to a part store or something and find an oring that would fit these things and hoping they will stay put and still work out. Anyone else have any experience with this or have any advice!?? Thanks a lot guys and I love you!
